Ruby下使用OpenSSL lib DES對稱式加密輸出
Sample Code如下:
===================================
#!/usr/bin/ruby
require "openssl"
class Encrypt
KEY = "abcdefghijklmnopqrstuvwxyz"
IV = "asdasdasdasdasdasdasdasdas"
CIPHER = "DES" #CIPHER是使用的加密方法
def des_encrypt(plaintext)
c = OpenSSL::Cipher::Cipher.new(CIPHER)
c.encrypt
c.key = KEY
c.iv = IV
ret = c.update(plaintext)
ret << c.final
end
def des_decrypt(encrypt_value)
c = OpenSSL::Cipher::Cipher.new(CIPHER)
c.decrypt
c.key = KEY
c.iv = IV
ret = c.update(encrypt_value)
ret << c.final
end
end
def gotorun
e = Encrypt.new
source = "a secret message"
puts "source :#{source}"
value = e.des_encrypt(source)
puts "encode :#{value}"
puts "encode hex:#{value.unpack('H*')[0]}"
puts "decode hex:#{[value.unpack('H*')[0]].pack('H*')}"
des_decrypt = e.des_decrypt(value)
puts "decode :#{des_decrypt}"
end

It’s robust, has good dimensional stability, it resists impacts and scratching, and is hard to interrupt. It’s generally used to produce electronic components corresponding to telephone adaptors, keyboard keys, and wall socket plastic guards. Because ABS is an efficient insulator and won’t conduct electricity or give off fumes if it’s uncovered to fire. These are important issues for product developers engaged on electrical devices. Luggage Sets Nylon is commonly used to produce robust mechanical components like bushings, gears, and bearings.
