封闭类:

ECKey

public static class ECKey.ECDSASignature
extends java.lang.Object

Groups the two components that make up a signature, and provides a way to encode to Base64 form, which is how ECDSA signatures are represented when embedded in other data structures in the Ethereum protocol. The raw components can be useful for doing further EC maths on them.

ECDSASignature

public ECDSASignature(java.math.BigInteger r,
                      java.math.BigInteger s)

Constructs a signature with the given components. Does NOT automatically canonicalise the signature.

参数:

r - -

s - -

方法详细资料

fromComponents

public static ECKey.ECDSASignature fromComponents(byte[] r,
                                                  byte[] s,
                                                  byte v)

参数:

r - -

s - -

v - -

返回:

-

validateComponents

public boolean validateComponents()

validateComponents

public static boolean validateComponents(java.math.BigInteger r,
                                         java.math.BigInteger s,
                                         byte v)

decodeFromDER

public static ECKey.ECDSASignature decodeFromDER(byte[] bytes)

toCanonicalised

public ECKey.ECDSASignature toCanonicalised()

Will automatically adjust the S component to be less than or equal to half the curve order, if necessary. This is required because for every signature (r,s) the signature (r, -s (mod N)) is a valid signature of the same message. However, we dislike the ability to modify the bits of a Ethereum transaction after it's been signed, as that violates various assumed invariants. Thus in future only one of those forms will be considered legal and the other will be banned.
