generate 1024 bit hashes on android

I am currently looking into ways of generating one way hashes to share sensitive information like开发者_如何学JAVA passwords to a web application backend.

Based on the documentation I cannot find any hashing algorithms that are supported by android OS that are larger than 512.

Are there any 1024 bit hashing algorithms for android?

If you'll pardon my being blunt, I think you're being a bit silly. If you stand any chance of having a use for a 1024-bit hash, your NSA liaison will tell you what to do. If what you're protecting doesn't have (at least) serious national security implications, a 1024-bit hash is pointless and silly.
