DECRYPT(1e)

NAME

decrypt - Decrypts a value with an algorythm.

SYNOPSIS

decrypt(key:12345678,value:"123"[,algo:blowfish,error:var])

PARAMETERS

number

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. 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.It supports cast5, aes, aes192, twofish128, des(not secure)

Encryption algorythm. Default blowfish.

RETURN

Returns decrypted string, array, context or null.

EXAMPLES

Note: In the followings examples, the _ between the { should be removed to make it work.
