I'm looking for solditiy-code to generate hashes of different hash-algorithms

  • MD5
  • SHA1
  • SHA512

and more. Is there any project which implemented hash-algorithms in solidity?

Is there someone out there who also needs this?

A pure Solidity version of SHA1 can be found in this repository. (See sha1.sol to jump to the code.)

From the README:

Pure-solidity implementation of the SHA1 hash function, heavily optimised using inline-assembly.

Gas consumption is approximately 56k per 512 bit block.

Solidity implements several hash function:

  • RIPEMD-160
  • SHA-256
  • Ethereum-SHA-3 (Keccak-256)

You can find additional information on the solidity website.
