Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Abstract: In information security, message authentication is an essential technique to verify that received messages come from the alleged source and have not been altered. A key element of ...

To strengthen the deterministic hash algorithm present in the RFC, sender timestamp should be a part of the deterministic message hash computation. As discussed in the vac research/doc vacp2p/rfc#632.

We used MD5 in the prepo hash-generation code simply “because it was there”: LLVM had a pre-existing implementation which meant that we could get started quickly. However, MD5 is “ cryptographically ...

Abstract: Presents a new proposed message digest (MD) algorithm. Many of its characteristics (application domain, performance and implementation structure) are similar to those of the MD4 family of ...
