Source: Internet
Author: User

Implementation Code:

Copy codeThe Code is as follows:
Class Des
Require 'openssl'
Require 'base64'
ALG = 'des-EDE3-CBC'
KEY = "mZ4Wjs6L"
DES_KEY = "nZ4wJs6L"

# Encryption
Def encode (str)
Des = OpenSSL: Cipher. new (ALG)
Des. pkcs5_keyivgen (KEY, DES_KEY)
Des. encrypt
Cipher = des. update (str)
Cipher <des. final
Return Base64.encode64 (cipher) # Base64 encoding before it can be saved to the database
End

# Decryption
Def decode (str)
Str = Base64.decode64 (str)
Des = OpenSSL: Cipher. new (ALG)
Des. pkcs5_keyivgen (KEY, DES_KEY)
Des. decrypt
Des. update (str) + des. final
End
End

Test code:

 Copy codeThe Code is as follows: require 'pp'
Des = Des. new
Str = '000000'
Pp '= encrypt ='
Str = des. encode (str)
Pp str

Pp '= decrypt ='
Pp des. decode (str)
