In public key infrastructure (PKI) systems, a certificate signing request (CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate.
The ElGamal signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms.It was described by Taher Elgamal in 1985. [1]The ElGamal signature algorithm is rarely used in practice.
Later Alice wants to sign a message. First she hashes the message to a 256-bit hash sum. Then, for each bit in the hash, based on the value of the bit, she picks one number from the corresponding pairs of numbers that make up her private key (i.e., if the bit is 0, the first number is chosen, and if the bit is 1, the second is chosen).
In cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm that was described by Claus Schnorr.It is a digital signature scheme known for its simplicity, among the first whose security is based on the intractability of certain discrete logarithm problems.
