WebKey size. In cryptography, key size, key length, or key space refer to the number of bits in a key used by a cryptographic algorithm (such as a cipher ). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be ... WebJul 18, 2024 · SSL Labs uses the terms DH public server param (Ys) and ECDH public server param for this.
