RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure.

RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure. It was developed by Ronald Rivest in 1989 with an algorithm which was optimized for 8-bit computers.

How is the MD2 hash function S-table constructed from Pi?

For fun, I'm learning more about cryptography and hashing. I'm implementing the MD2 hash function following RFC 1319 (https://www.rfc-editor.org/rfc/rfc1319). I'll preface by saying I know there are libraries, I know this is an old hash, and I do…

Why did MD4 replace MD2?

MD2 was a hash function based on swapping bytes in a state array permutation, much like the RC4 stream cipher, whereas MD4 was a novel construction. MD4 replaced MD2 despite the fact that MD4 is more badly broken. Even MD5, an improvement upon MD4,…

Is text description of MD2 algorithm wrong?

I'm trying to implement MD2 from scratch of RFC 1319. It feels like there is a gap between steps 3.2 & 3.3. After step 2, the checksum C is appended to the message and never mentioned again. We start 18 rounds of XOR-ing for each block using MD…
