Malicious SHA-1TL;DR: If the four 32-bit constants of SHA-1 can be modified, then exploitable collisions can be constructed. No need to panic, this doesn’t affect the original SHA-1. However, vendors and customers of products with custom cryptography will be interested. Summary This is the webpage of the Malicious SHA-1 project, a research project that demonstrates how the security of the SHA-1 hashing standard
