If the SHA1 hash for the downloaded chunk doesn't match the SHA1 hash included in the torrent file, the downloaded data is discarded. On top of these, the torrent files themselves have a SHA1 hash, ...

Sorry, I wasn't explaining myself clearly. Rather than have a new-hash commit that's a child of an old-hash commit, maintain two complete sets of commits/history, one ...

Cryptographic hash functions are widely used in many aspects of security, such as digital signatures and data integrity checks. The short digital fingerprint generated from an electronic file, message ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

A recently announced SHA-1 collision attack has the potential to break code repositories that use the Subversion (SVN) revision control system. The first victim was the repository for the WebKit ...

The SHA-1 hash algorithm has been known for at least a decade to be weak; while no generated hash collisions had been reported, it was assumed that this would happen before too long. On February 23, ...
