使用ruby中的openpgpgem进行三层加密和解密-tripledesencryptionanddecryptionusingopenpgpgeminruby

You're probably thinking of openssl, not openpgp. Here's a documentation of openssl encryption functions in ruby. You can also use the much simpler gibberish module. You need Ruby compiled with openssl support either way; either compile it yourself or find one available for download.

您可能想到的是openssl，而不是openpgp。下面是ruby中openssl加密功能的文档。您还可以使用更简单的gibberish模块。无论哪种方式，都需要使用openssl支持编译的Ruby;可以自己编译，也可以下载。

If it absolutely has to be Triple DES, here's how you would obtain an instance with the OpenSSL extension:

如果它必须是三重DES，那么您可以通过OpenSSL扩展获得一个实例:

cipher = OpenSSL::Cipher::Cipher.new("des-ede-cbc")
cipher.encrypt
key = cipher.random_key
iv = cipher.random_iv
...

Please ensure to call random_key and random_iv as illustrated here and in the docs that SilverbackNet already mentioned. In there, you will also find an example on how to do the actual encryption and decryption.

请确保调用random_key和random_iv，如这里所示，以及SilverbackNet已经提到的文档中。在那里，您还将找到一个关于如何进行实际的加密和解密的示例。

If you are free to choose the algorithm, you might want to choose AES over Triple DES, it's a lot faster and generally considered a more modern cipher.

如果你可以自由选择算法，你可能想要选择AES而不是三倍，它的速度更快，通常被认为是一个更现代的密码。
