Method Detail

sign

Signature sign(byte[] data)

Signs the hash of an arbitrarily sized message.

Parameters:

data - The message to sign.

Returns:

The generated signature.

verify

boolean verify(byte[] data,
               Signature signature)

Verifies that the signature is valid.

Parameters:

data - The original message.

signature - The generated signature.

Returns:

true if the signature is valid.

isCanonicalSignature

boolean isCanonicalSignature(Signature signature)

Determines if the signature is canonical.

Parameters:

signature - The signature.

Returns:

true if the signature is canonical.

makeSignatureCanonical

Signature makeSignatureCanonical(Signature signature)

Makes this signature canonical.

Parameters:

signature - The signature.

Returns:

Signature in canonical form.
