SHA-1 deprecation countdown
The SHA-1 hash algorithm is no longer secure. Weaknesses in SHA-1 could allow an attacker to spoof content, execute phishing attacks, or perform man-in-the-middle attacks when browsing the web. Microsoft, in collaboration with other members of the industry, is working to phase out SHA-1. We have outlined our timeline for SHA-1 deprecation in earlier posts, most recently in April. This post is to c
SHA1 weakness benefits password crackers - The H Security: News and Features
Jens Steube, a co-author of the popular Hashcat password cracker, has discovered a weakness in the SHA1 cryptographic hashing technique that enables him to accelerate password cracking by about 20 per cent. SHA1 always processes blocks of 512 bits (64 bytes). However, this data is expanded to 2,048 bits when the SHA1 hash value is generated – Steube calls this process "word expansion". Words are e
