@param k Threshold @param n Number of shares @param seed seed value for CSPRNG @param ski Secret key to be shared. @param x x values @param y y values. Valid BLS secret keys @param rc Zero for success or else an error code
func BLSRecoverSecret ¶
BLSRecoverSecret Use Shamir's secret sharing to recover a BLS secret key
Use Shamir's secret sharing to recover a BLS secret key ¶
@param k Threshold @param x x values @param y y values. Valid BLS secret keys @param sk Secret key that is recovered @param rc Zero for success or else an error code
func BLSRecoverSignature ¶
BLSRecoverSignature Use Shamir's secret sharing to recover a BLS signature
Use Shamir's secret sharing to recover a BLS signature ¶
@param k Threshold @param x x values @param y y values. Valid BLS signatures @param sig Signature that is recovered @param rc Zero for success or else an error code
func BLSSign ¶
BLSSign Sign a message
The message is signed using the BLS algorithm @param M Message to be signed @param sk secret key @param S Signature @param rc Return code. Zero for success or else an error code
func BLSVerify ¶
BLSVerify Verify a signature
Verify a signature using the BLS algorithm @param M Message that was signed @param pk public key @param S Signature @param rc Return code. Zero for success or else an error code
func DecapsulateDecrypt ¶
DecapsulateDecrypt Decapsulate the AES Key and decrypt the message
Decapsulate the AES key and use it to decrypt the ciphertext. The plaintext is returned using the C parameter.
