WebCiphers are arguably the corner stone of cryptography. In general, a cipher is simply just a set of steps (an algorithm) for performing both an encryption, and the corresponding decryption. Despite might what seem to be a relatively simple concept, ciphers play a crucial role in modern technology. Webcipher. One of the MCRYPT_ciphername constants, or the name of the algorithm as string. key. The key with which the data will be encrypted. If the provided key size is not supported by the cipher, the function will emit a warning and return false. data. The data that will be encrypted with the given cipher and mode.
