Is there an algorithm that computes the strength of a digest alg? (original) (raw)

Hi Andrew

I need a method

boolean isWeakerThan(String a1, String a2)

so that isWeakerThan("MD5", "SHA1") returns true and isWeakerThan("SHA-256", "SHA1") returns false. I know you have done a lot of constraints works in JDK 7. Do you have an existing one? Otherwise, I plan to manually assign a value to each known algorithm and compare it.

Thanks Max
