public ECSignature(r: *, s: *) source 

import ECSignature from 'bitsharesjs/lib/ecc/src/ecsignature.js'

Params:

NameTypeAttributeDescription
r *
s *

public HmacSHA256(buffer: *, secret: *): * source 

import {HmacSHA256} from 'bitsharesjs/lib/ecc/src/hash.js'

Params:

NameTypeAttributeDescription
buffer *
secret *

Return:

*

public calcPubKeyRecoveryParam(curve: *, e: *, signature: *, Q: *): * source 

import {calcPubKeyRecoveryParam} from 'bitsharesjs/lib/ecc/src/ecdsa.js'

Calculate pubkey extraction parameter.

When extracting a pubkey from a signature, we have to distinguish four different cases. Rather than putting this burden on the verifier, Bitcoin includes a 2-bit value with the signature.

This function simply tries all four cases and returns the value that resulted in a successful pubkey recovery.

Params:

NameTypeAttributeDescription
curve *
e *
signature *
Q *

Return:

*

public convert(type: *): * source 

import convert from 'bitsharesjs/lib/serializer/src/convert.js'

Params:

type *

Return:

*

public recoverPubKey(curve: *, e: *, signature: *, i: *): * source
