->32-bytes clj

(->32-bytes k)

Pad 0s into a private key to have 32 bytes.

->33-bytes clj

(->33-bytes k)

Pad 0s into a private key to have 33 bytes.

add-point clj

(add-point Ki IL)

Add two points in the curve. Ki is a compressed public key. IL is a private key.

compress-public-key clj

(compress-public-key K)

Compress a public key K. Start with 02 if the Y part of the public key is even and 03 otherwise.

CURVE clj

secp256k1 curve

CURVE_PARAMS clj

parameters of the secp256k1 curve

decompressKey clj

(decompressKey xBN yBit)

Decompress a compressed public key (x co-ord and low-bit of y-coord). xBN: public key in BigInteger format. yBit: parity bit 0x02 if the Y is even and 0x03 otherwise. Reference: https://github.com/web3j/web3j/blob/master/crypto/src/main/java/org/web3j/crypto/Sign.java#L208

deserialize-base58 clj

(deserialize-base58 encoded-key)

Deserialize a base58 encoded key.

encode-base58 clj

(encode-base58 master-key)

Encode a serialized key into base58.

group-add clj

(group-add k-par IL)

Field addition of two numbers. The result is k-par + IL mod N.

hardened clj

(hardened index)

Return the a hardened index.

hardened? clj

(hardened? path-part)

Tell if part of a path is hardened (terminated by H).

key-fingerprint clj

(key-fingerprint K)

Compute the fingerprint of a public key K. Reference: https://github.com/web3j/web3j/blob/49fe2c4e2d9d325ec465879736d6c384f41a4115/crypto/src/main/java/org/web3j/crypto/Bip32ECKeyPair.java#L131

key-identifier clj

(key-identifier K)

Compute the identifier of a public key K.

legacy-address clj

(legacy-address K network)

Encode a public key into a legacy Bitcoin address. K is the public key. network is either :mainnet or :testnet.

pad-leading-zeros clj

(pad-leading-zeros n k)

private->public-key clj

(private->public-key privKey)

Compute a public key from the given private key. Reference: https://github.com/web3j/web3j/blob/master/crypto/src/main/java/org/web3j/crypto/Sign.java#L322

private->public-point clj

(private->public-point privKey)

Returns public key point from the given private key. Reference: https://github.com/web3j/web3j/blob/master/crypto/src/main/java/org/web3j/crypto/Sign.java#L335

serialize clj

(serialize network type depth fingerprint child-number chain-code key-data)
