DECRYPT
NAME
decrypt - Decrypts a value with an algorythm.
SYNOPSIS
decrypt(key:12345678,value:"123"[,algo:blowfish,error:var])
PARAMETERS
- Encryption key value
- The encrypted value the user wants to decrypt.
-
- Encryption algorithm
- The algorithm used for the encryption. By default, the used algorithm is Blowfish. It supports cast5, aes, aes192, twofish128, des(not secure).
-
- Error
- If the user specified an error variable, then this variable will contain "errorcode" or "errmsg". If the "errorcode" is not zero, then there is an error.
RETURN
- Returns decrypted string, array, context or null.
EXAMPLES
Note: In the followings examples, the _ between the { should be removed to make it work.
