问题描述
我需要使用完全PKCS＃1 V2.0加密方法（在）。
I need encrypt data using exactly the PKCS#1 V2.0 encryption method (defined in item 7.2.1 of the PKCS#1V2 specification).
Java已经实现了吗？
Is it already implemented for Java?
我正在考虑一些事情，例如将参数传递给指定PKCS＃1V2的javax.crypto.Cipher，我想知道是否有这样的东西？
I'm thinking in something like just pass a parameter to javax.crypto.Cipher specifying "PKCS#1V2", I wonder if there is something like this?
推荐答案
PKCS＃1 v2.0加密通常称为OAEP加密。所以：
PKCS#1 v2.0 encryption is usually called OAEP encryption. So:
Cipher.getInstance("RSA/ECB/OAEPWithSHA1AndMGF1Padding");
要查看的地方是Java加密体系结构文档：或。
The place to look is the Java Cryptography Architecture documents: Standard Algorithm Name Documentation or Sun Providers Documentation.
您可以看到SunJCE提供商支持OAEP的以下变体：
As you can see the SunJCE provider supports the following variations of OAEP:
- OAEPWITHMD5ANDMGF1PADDING
- OAEPWITHSHA1ANDMGF1PADDING
- （OAEPWITHSHA-1ANDMGF1PADDING）
- OAEPWITHSHA-256ANDMGF1PADDING
- OAEPWITHSHA-384ANDMGF1PADDING
- OAEPWITHSHA-512ANDMGF1PADDING
- OAEPWITHMD5ANDMGF1PADDING
- OAEPWITHSHA1ANDMGF1PADDING
- (OAEPWITHSHA-1ANDMGF1PADDING)
- OAEPWITHSHA-256ANDMGF1PADDING
- OAEPWITHSHA-384ANDMGF1PADDING
- OAEPWITHSHA-512ANDMGF1PADDING
