how to get PHP and Delphi encryption to work together. The idea behind DCPcrypt is that it shoshould be possible to "drop in" any algorithm implementation to replace another with minimum or no code changes. to aid in this goal all cryptographic components are descended from one of several base classes, TDCP_cipher for encryption algorithms and TDCP_hash for message digest algorithms. DCPcrypt v2 contains f

encryption algorithm standard with fast speed and high security level. Currently, one of the implementations of the AES standard is the Rijndael algorithm; Blowfish uses a variable-length key, which can contain up to 448 bits and runs fast; Other algorithms, such as ElGamal, deffie-Hellman, and ECC. 2. Unidirectional hashing algorithm Unidirectional hash functions are generally used to generate message sum

is 04-31, and exceeding this range will cause crypt () to fail.The crypt_sha256-sha-256 algorithm uses a 16-character string salt value that begins with $5$ to hash. If the salt value string begins with "rounds= $", the numeric value of N is used to specify the number of executions of the hash loop, much like the cost parameter of the Blowfish algorithm. The default number of cycles is 5000, the minimum is 1000, and the maximum is 999,999,999.

N is used to specify the number of execution times of the hash loop, which is similar to the cost parameter of the Blowfish algorithm. The default number of cycles is 5000, the minimum is 1000, and the maximum is 999,999,999. N out of this range will be converted to the nearest value. CRYPT_SHA512-the SHA-512 algorithm hashes salt values from a 16-character string starting with $6 $. If the salt value string is "rounds = Starting with $, the
