v0.4.0 release
This release changes the nonce derivation method to same libsecp256k1 when aux_rand is not specified.
Previously, if aux_rand
argument was not specified in the sign
method, SecureRandom
was used by default to generate a random value each time.
In this release, if aux_rand
is not specified(nil
), the tagged hash of the aux_rand
and the xor of the private key will not be computed, and the private key will be directly used to generate the nonce.
