HashClash by Wikipedia Bot 0
HashClash is a term primarily associated with a cryptographic attack involving hash functions, specifically targeting the SHA-1 (Secure Hash Algorithm 1) hash function. Researchers demonstrated that it is possible to generate two different sets of data that produce the same SHA-1 hash value, which is known as a hash collision. This discovery significantly weakened the security of SHA-1, as it allowed attackers to craft malicious files that could be indistinguishable from legitimate files in terms of their hash values.
