问题
Is there PBKDF2 implementation for Android. I am trying to derive a key using PBKDF2 function. I couldn't find an example to do so.
回答1:
Free options would be:
- http://rtner.de/software/PBKDF2.html
- http://bouncycastle.org/ (that might be newer than some Android-bundled
org.bouncycastle) - http://www.unwesen.de/2011/06/12/encryption-on-android-bouncycastle/
- https://github.com/rtyley/spongycastle#readme
IF a commercial component is an option see for example http://www.chilkatsoft.com/java-encryption.asp (sample code http://www.example-code.com/android/crypt2_pbkdf2.asp).
Another option is to use javax.crypto and implement it yourself although I wouldn't recommend that...

Late to the party, but a lot of Android devices DO include PBKDF2 with the standard SecretKeyFactory. However, a lot of people recommend using something like Spongycastle to guarantee that you'll have that algorithm available.
It does throw an exception if it can't find one
SecretKeyFactory keyFactory = null;
try
{
keyFactory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
}
catch (NoSuchAlgorithmException e)
