crypt

Encrypt a value with an algorythm.

CRYPT

NAME

crypt - Encrypts a value with an algorythm.

SYNOPSIS

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

PARAMETERS

Encryption key value (has to be at least 16 characters)

Encryption value. It can be a string, context, or array

algo Encryption algorythm.

By default, it is set to "blowfish". It supports cast5, aes, aes192, twofish128, des(not secure)

error

If you specified an error variable, then this variable will contain errcode and errmsg. If errcode is not 0, then there is an error. This does not trap error with parameterso

Output is encode in base64 (with these characters : ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789:-)

Code is based on library gcrypt (https://gnupg.org/software/libgcrypt/index.html)

RETURN

String: Returns the encrypted string.

EXAMPLES

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