📝 Original message:Hi everyone,

We've been hard at work updating the spec to include features that were requested. We've removed the Scrypt dependency that was present in the initial drafts, added new KDFs, added plausible deniability and have a reference implementation.


Kind regards,

BIP:
Title: Base58 encoded HD Wallet root key with optional encryption
Author: Jean-Paul Kogelman
Status: Draft
Type: Informational
Created: 18-07-2013

Abstract

This proposal describes a method for encoding and optionally encrypting a Bitcoin Hierarchical Deterministic (HD) Wallet root key. Encoded root keys are intended for use on paper wallets. Each string contains all the information needed to verify and reconstitute an HD wallet except for the optional passphrases. The encrypted version uses salting and a user selectable key derivation function (KDF) + parameters to resist brute-force attacks at varying degrees and optionally a second password for plausible deniability.

The method provides two encoding methodologies in 3 lengths each (16, 32 and 64 byte root keys). One is a clear version of the root key with verification information for integrity checking and the other is an encrypted representation.

Additionally a 2 byte compressed date field is present to limit the block chain rescan on wallet import.


Motivation

The extended private keys proposed in BIP 0032 are long, fixed length records and don't offer any form of security. The root key used to generate the HD wallet is typically shorter than the extended master private key that results from it.

A compact representation of the root key is easier to handle and a 2-factor version of the root key record allows for safe storage and the creation of paper wallets by 3rd parties. The KDF and its parameters are user selectable, allowing for a varying level of resistance against brute force attacks. This proposal currently defines 5 sets of parameters with room for 27 more that can be defined at a later date. Implementors are advised to contact the author with new KDF proposals.

This proposal is hereby placed in the public domain.

Rationale

User story: As a Bitcoin user who uses HD wallets, I would like the ability to store my wallet root key in a compact form as a paper wallet.

User story: As a Bitcoin user who uses HD wallets, I would like the ability to have a 3rd party create a paper wallet with my root key in it, without having access to the funds stored in the wallet.

User story: As a Bitcoin user who uses HD wallets, I would like the ability to choose the strength of the root key depending on my security requirements and how I wish to store it.

User story: As a Bitcoin user who uses HD wallets, I would like the ability to import a root key into a simplified payment verification (SPV) client without having to redownload the entire block chain, but rater a limited range, to find associated transactions.

User story: As a Bitcoin user who uses HD wallets, I would like to choose the KDF and its parameters that is used to hash the passphrase that protects my root key to fit my security needs and available processing power.

User story: As a Bitcoin user who uses HD wallets, I would like to outsource the KDF computation to a 3rd party with more processing power.

User story: As a Bitcoin user who uses HD wallets, I would like to have a second password that can decrypt a second root key.

Specification

This proposal makes use of the following functions and definitions:

All input/output text is to be UTF-8 encoded

AES256Encrypt, AES256Decrypt: The AES block cipher, applied in ECB mode.

SHA256, SHA512: The hash algorithms of the same name.

HMAC-SHA512: The HMAC message authentication code algorithm, using SHA512 as the hash function

PBKDF2-HMAC-SHA512: The PBKDF2 key derivation algorithm, described in PKCS #5 v2.0 and RFC 2898, using HMAC-SHA512 as the pseudorandom function

Scrypt: The key stretching algorithm of the same name

Base58Check: The textual data encoding frequently used by various Bitcoin-related systems

"Root Key": The 16/32/64 byte value encoded in the wallet. This value is used to derive the private keys for addresses in the Bitcoin Wallet

"Master Key": The primary Bitcoin private key, which is derived from the Root Key

"||" refers to concatenation, not the logical OR operation

"G", "N": Constants defined as part of the secp256k1 elliptic curve. G is an elliptic curve point, and N is a large positive integer.

Prefix

The Base58Check representation of the wallet will start with "RK" (Root Key) if the wallet is unencrypted, and will start with "rk" if the wallet is encrypted.

Proposed specification

Unencrypted wallet:

Prefixes:
0x28C1: 16 byte root key, no encryption. 24 byte total length
0x4AC5: 32 byte root key, no encryption. 40 byte total length
0xFBB3: 64 byte root key, no encryption. 72 byte total length

These are constant bytes that appear at the beginning of the Base58Check-encoded record, and their presence causes the resulting string to have a predictable prefix.

"date" is a 2-byte, little endian field containing the number of weeks since jan 1st 2013. It is used to optimize blockchain scan upon wallet import.

"checksum" is the first 4 bytes of SHA256(SHA256(master_secret)), where master_secret is the "Master Secret Key (IL)" from the BIP32 specification. In other words, "checksum"=SHA256(SHA256(HMAC-SHA512("Bitcoin seed", root_key)[0:32]))[0:4].

"root_key" is the 16/32/64 byte root key used for the HD wallet

In summary, the clear wallet looks like this:
[prefix, 2 bytes][date, 2 bytes][checksum, 4 bytes][root_key, 16/32/64 bytes]

Range in Base58Check encoding for clear 16 byte root key (prefix RK):
Minimum value: RK52zvuD3xRhwto8JDTonxhru6awsFfNqKCTmT (based on 0x28 0xC1 plus twenty-two 0x00's)
Maximum value: RKCsfF9RpLnrxo1kp2o7mfWYeAV1NNYxWSMRym (based on 0x28 0xC1 plus twenty-two 0xFF's)

Range in Base58Check encoding for clear 32 byte root key (prefix RK):
Minimum value: RK15fXAj9BEMooghtx2gY5YrSh23LYKS8mZnaz8oYf1EDnqAwtAADGMVUDHG (based on 0x4A 0xC5 plus thirty-eight 0x00's)
Maximum value: RK5MUEoFU24QARcsX5HR2ieCjem468hDeQm4J2aH5zsCVJXUCGn6nsVQEFhN (based on 0x4A 0xC5 plus thirty-eight 0xFF's)

Range in Base58Check encoding for clear 64 byte root key (prefix RK):
Minimum value: RK1uXsCQAKqaa2s7YBDeaLS2KTqZcNjjQSgdSfDv4fqGkTw8KBfZ2ND4Cp7vHdzhjJ2C2Jtf4CwgScRnXvpzuQT2W4Vj2SgCyfBgpTzF (based on 0xFB 0xB3 plus seventy 0x00's)
Maximum value: RK3B9TMn55dey3an1oHpwB81FPZboakivYtqFvCaeknPzPK4iTvoFKzxVWKcD9YfJwjkyS36bqnSqjibUurcQ7J2EsQww5zPpJNzqjkw (based on 0xFB 0xB3 plus seventy 0xFF's)


Encrypted wallet:

Prefixes:

0xF83F: 16 byte root key, encrypted. 26 byte total length
0x6731: 32 byte root key, encrypted. 43 byte total length
0x4EB4: 64 byte root key, encrypted. 76 byte total length

These are constant bytes that appear at the beginning of the Base58Check-encoded record, and their presence causes the resulting string to have a predictable prefix.

"date" is a 2-byte, little endian field containing the number of weeks since jan 1st 2013. It is used to optimize blockchain scan upon wallet import. The maximum value of 0xFFFF results in: jan 1st 3269

"entropy" is a 2/3/4 byte (corresponding to whether the key is 16/32/64 bytes) field. The first five bits contain the KDF type, and all other bits contain random data. This is used as a salt to make cracking the wallet password harder.

"bloom_filter" is a 4 byte little-endian field containing a bloom filter to check that the user entered their password correctly.

"encrypted_root_key" is the 16/32/64 byte encrypted root key used for the HD wallet

In summary, the encrypted wallet looks like this:
[prefix, 2 bytes][date, 2 bytes][entropy, 2/3/4 bytes][bloom_filter, 4 bytes][encrypted_root_key, 16/32/64 bytes]


Range in Base58Check encoding for encrypted 16 byte root key (prefix rk):
Minimum value: rk2V4R2ys91WigNPL5nots6a97rfMnwTkPAb2XgNo (based on 0xF8 0x3F plus twenty-four 0x00's)
Maximum value: rk57mv9oertBLsHfncAvqnbetCBdNS1gFHQaFsD3p (based on 0xF8 0x3F plus twenty-four 0xFF's)

Range in Base58Check encoding for encrypted 32 byte root key (prefix rk):
Minimum value: rk1CYsqKjsbXa7uvncEaW4XSeVzcpq1U9yDMxd2cWwfkGf1FMjENaVThYpLRNwqo (based on 0x67 0x31 plus fourty-one 0x00's)
Maximum value: rk7Xw5b6fidaCk489LhaiMqHkZo7RYGTmzvJY9A5joxe8KXAn8BC66cmQPYYYvy8 (based on 0x67 0x31 plus fourty-one 0xFF's)

Range in Base58Check encoding for encrypted 64 byte root key (prefix rk):
Minimum value: rk48BmQWeQbATSXbP5U6XVsXRJTs4Ea1TVZBbHLPPsboCFyxDj2Jaz2JAJno97hq6dq2bANLuWydY8QSZgKVGhPRZazXt1swPXwzVLw1QnVAz (based on 0x4E 0xB4 plus seventy-four 0x00's)
Maximum value: rkCRtT9R9kuAapCaLQFif5uo8gUrjgKsvYmGGTpX2ZTjTfwe9M7A6KezTh7f4FDxfZFVbHypodMNnNdmWYb8mzTokHXVR1u7KicrLLFFu7GJW (based on 0x4E 0xB4 plus seventy-four 0xFF's)


Encoding of KDF + parameters:

A number of KDF functions are available, to accommodate a wide range of possible use cases. The KDFs are defined as follows:

ID KDF Parameters
0x00 scrypt n = 2^14, r = 8, p = 8
0x01 scrypt n = 2^16, r = 16, p = 16
0x02 scrypt n = 2^18, r = 16, p = 16
0x08 PBKDF2-HMAC-SHA512 iterations = 216
0x09 PBKDF2-HMAC-SHA512 iterations = 221

All other possible values (3-7 and 10-31) are reserved.

Please note that KDFs 1 and 2 will probably not run on mobile devices. KDFs 8 and 9 are very memory efficient.

Generation of date:

The purpose of the date field is to make scanning the blockchain for transactions to/from this wallet faster. The date *must* be on or before the date of the first transaction to/from the wallet. If the date is unknown (e.g. on an embedded device) or the user does not wish to reveal the wallet creation date, this field can be set to zero (which may incur a performance penalty for the wallet software). When importing, it is advised to start scanning from a few days before the encoded date. The date field is a little-endian integer containing the number of weeks, rounded down, since Jan 1st 2013.

Examples:

sep 18th 2013 - jan 1st 2013 = 260 days = 37 weeks 1 day = rounded down becomes 0x0025
mar 3rd 2027 - jan 1st 2013 = 5174 days = 739 weeks 1 day = rounded down becomes 0x02E3

Derivation of Master Key from Root Key (please see BIP 0032 for a full description of HD wallets):

1. Take 16/32/64 byte Root Key. Call it S
2. Calculate I = HMAC-SHA512(key = "Bitcoin seed", msg = S)
3. Let IL = I[0:32]. IL is the Master Key
4. If IL is 0 or IL >= N, where N is the curve order of Secp256k1 (the elliptic curve used by Bitcoin), the Root Key is invalid and a new one should be chosen.

Encryption:

Let "passphrase" be the user's chosen passphrase
Let "fake_passphrase" be the user's chosen second passphrase, or a randomly generated string if the user chose not to use a second passphrase
Let "KDF" be the chosen key derivation function
Let "root_key" be the 16/32/64 byte Root Key

1. Create the correct "Prefix" and "Date" field
2. Create the random "Entropy" field and encode the KDF number in the top 5 bits
3. Let "salt" = Prefix || Date || Entropy
4. Calculate "preH" = HMAC-SHA512(key = salt, msg = passphrase)
5. Calculate "strongH" = KDF(msg = preH, salt = preH, output_len = 64) This step can be outsourced to a 3rd party, if desired.
6. Calculate "postH" = HMAC-SHA512(key = passphrase, msg = salt)
7. Calculate "H" = PBKDF-HMAC-SHA512(msg = postH, salt = strongH, iterations = 210, output_len = len(root_key) + 32)
8. Calculate "whitened_key" = root_key XOR H[0:len(root_key)]
9. Calculate "encrypted_key" = AES256Encrypt(message = whitened_key, key = HR), where HR is the last 32 bytes of H
10. Calculate "fake_key" by decrypting encrypted_key with fake_passphrase
11. Calculate "bloom_filter", containing root_key and fake_key. See the "Bloom Filter" section for more info.

encrypted_wallet = Prefix || Date || Entropy || bloom_filter || encrypted_key

Decryption of Root Key:

Let "passphrase" be the passphrase provided by the user

1. Extract "Prefix", "Date", "Entropy", "bloom_filter", and "encrypted_key" from the encrypted wallet
2. Determine the correct KDF from the top 5 bits of Entropy.
3. Let "salt" = Prefix || Date || Entropy
4. Perform steps 4 through 7 of Encryption to derive "H"
5. Calculate "whitened_key" = AES256Decrypt(message = encrypted_key, key = HR), where HR is the last 32 bytes of H
6. Calculate "root_key" = whitened_key XOR H[0:len(whitened_key)]
7. Verify that root_key is a member of bloom_filter

Bloom Filter:

The Bloom Filter is a data structure that allows us to check, within a range of probability, whether or not some piece of data has been added to it. In this case, we want to make sure that the user entered their password correctly, so we're checking that the decrypted root_key corresponds to the one that was added to the bloom filter when the wallet was created.

Bloom Filter Creation:

1. Let "bloom_filter" be an empty (set to all zeros) 32-bit, little-endian integer
2. To add an element "X" to bloom_filter,
3. Calculate "E" = SHA256(SHA256(HMAC-SHA512("Bitcoin seed", X)[0:32]))[0:11]. Note, this corresponds to the same algorithm used as a checksum for un-encrypted wallets. It also corresponds to the double-SHA of the Master Key.
4. For each of the 11 bytes in E (call each byte "B"):
4a. calculate "N" = B & 0x1F. N will range from 0 to 31. Set the Nth bit in bloom_filter to 1

You can add more items to the bloom filter, if desired. However, the filter parameters are optimized for 2 items (one "real" password/wallet, and one "fake" password/wallet). Please note that adding more items will drastically increase the chance of a false positive when entering a password. The chance of a password similar to a correct password passing the filter becomes more likely. This will generate a different Root Key and not the original one the user intended to decrypt.

Bloom Filter Verification:

Let "X" be some item
Let "bloom_filter" be the Bloom Filter you want to check if X belongs to

1. Calculate "x_only_filter", which is a Bloom Filter with X added to it
2. Ensure that any bit that is set in x_only_filter is also set in bloom_filter (i.e. x_only_filter & bloom_filter == x_only_filter)
3. If all bits set in x_only_filter are also set in bloom_filter, you know X is probably a member of bloom_filter. If not, X is definitely *not* a member of bloom_filter.

Suggestions for implementers of proposal with alt-chains

This proposal is network and coin agnostic (so long as the coin in question uses SECP256K1 ECC). Alt-coin implementors are advised to change the prefixes so that encoded root keys do not start with “RK" or “rk”.
