我有一段 Java 代码负责加密和解密,需要将其转换为 Ruby。在此处发帖之前,我通过了 4 个链接,但没有成功。

public static void main(String[] args) {
String encText = encrypt("abceeffslaj");
System.out.println("Decripted text :: " + decrypt("XZy6gJinORmH+LOiZL6/Jw=="));
}
}
Output:
Simple Text :: abceeffslaj
Encrypted text :: XZy6gJinORmH+LOiZL6/Jw==
Decripted Text :: abceeffslaj
为了得到相同的结果,我写了下面的代码
我的努力:Ruby
require "openssl"
require "base64"
require 'byebug'
include Base64
plain_text = "abceeffslaj"
cipher = OpenSSL::Cipher::AES128.new(:CBC)
cipher.encrypt
key = cipher.random_key
iv = cipher.random_iv
cipher_text = cipher.update(plain_text) + cipher.final
cipher = OpenSSL::Cipher::AES128.new(:CBC)
cipher.decrypt
cipher.key = key
cipher.iv = iv
decrypted_plain_text = cipher.update(cipher_text) + cipher.final
puts "AES128 in CBC mode"
puts "Key: " + urlsafe_encode64(key)
puts "Iv: " + urlsafe_encode64(iv)
puts "Plain text: " + plain_text
puts "Cipher text: " + urlsafe_encode64(cipher_text)
puts "Decrypted plain text: " + decrypted_plain_text
输出:
AES128 in CBC mode
Key: CJ-SNuUllNKl1vAllEazKg==
Iv: ZMb2W6K07oaAXuvoL8Ckpg==
Plain text: abceeffslaj
Cipher text: jyutt1ljXW9Xn-HFxpvcEg==
Decrypted plain text: abceeffslaj
我们可能会注意到这里的密文与 Java 代码不同。
非常感谢任何帮助!
最佳答案
您需要使用 Java 示例中的 IV 和 key ,而不是新的/随机的 IV/ key :
require "openssl"
require "base64"
require 'byebug'
include Base64
plain_text = "abceeffslaj"
key = 'Bar12345Bar12345'
iv = 'RandomInitVector'
cipher = OpenSSL::Cipher::AES128.new(:CBC)
cipher.encrypt
cipher.key = key
cipher.iv = iv
cipher_text = cipher.update(plain_text) + cipher.final
cipher = OpenSSL::Cipher::AES128.new(:CBC)
cipher.decrypt
cipher.key = key
cipher.iv = iv
decrypted_plain_text = cipher.update(cipher_text) + cipher.final
puts "AES128 in CBC mode"
puts "Key: " + urlsafe_encode64(key)
puts "Iv: " + urlsafe_encode64(iv)
puts "Plain text: " + plain_text
puts "Cipher text: " + urlsafe_encode64(cipher_text)
puts "Decrypted plain text: " + decrypted_plain_text
