问题
I need encrypt data using exactly the PKCS#1 V2.0 encryption method (defined in item 7.2.1 of the PKCS#1V2 specification).
Is it already implemented for Java?
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?
回答1:
PKCS#1 v2.0 encryption is usually called OAEP encryption. So:
Cipher.getInstance("RSA/ECB/OAEPWithSHA1AndMGF1Padding");
The place to look is the Java Cryptography Architecture documents: Standard Algorithm Name Documentation or Sun Providers Documentation.
As you can see the SunJCE provider supports the following variations of OAEP:
- OAEPWITHMD5ANDMGF1PADDING
- OAEPWITHSHA1ANDMGF1PADDING
- (OAEPWITHSHA-1ANDMGF1PADDING)
- OAEPWITHSHA-256ANDMGF1PADDING
- OAEPWITHSHA-384ANDMGF1PADDING
- OAEPWITHSHA-512ANDMGF1PADDING
