Linus Torvalds, Linux and Git's inventor, doesn't see any real security headaches ahead for you. SHA-1 may be vulnerable to attack but your Git-based source code is still safe for all practical

In addition, I compare Keccak against SHA-1 and SHA-2 using four standard tests. Readers should have a working knowledge of C and Objective-C, and a very basic understanding of encryption. Limitations of SHA-1 and SHA-2. A notable problem with SHA-1 and SHA-2 is that they both use the same engine, called Merkle-Damgard, to process message text. SHA-1 Security Certificate Vulnerability. 03/26/2020 22 11344. DESCRIPTION: As of January 1st, 2017, Certificate Authorities have unanimously stopped using SHA-1 certificates. This will result in browsers rejecting SHA-1 certificates. Any code which is signed after January 1st, 2016, is no longer trusted by Microsoft. can't be simply "Entity A is Act B because C", where C = Z (Qualys are saying SHA-1 based certs are weak because Google is going to warn about them because they are weak). The answer would be C' = Z' where those are the reason entities A and X are stating C and Z, respectively. – a CVn Sep 17 '14 at 19:44 SHA-1 in digital certificates and cryptographic keys hasn't been safe for years. With the world's first successful collision attack, the clock has run out for the hash function

SHA-1 is the most widely used of the existing SHA hash functions and is employed in several widely-deployed security applications and protocols. It’s a cryptographic computer security algorithm created by the National Security Agency (NSA) in 1995, and published by the NIST as a U.S. Federal Information Processing Standard.

SHA-1 or ‘Secure Hash Algorithm 1’ is a cryptographic hash function that has been used by certificate authorities to sign SSL certificates. The CA/B Forum has announced the deprecation of the SHA-1 algorithm in favor of the newer and more secure SHA-2 hashing algorithms. Security Hash Algorithm (SHA) was developed in 1993 by the National Institute of Standards and Technology (NIST) and National Security Agency (NSA).SHA-l is a revised version of SHA designed by NIST and was published as a Federal Information Processing Standard (FIPS).

Feb 23, 2017 · 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.

May 27, 2020 · OpenSSH to deprecate SHA-1 logins due to security risk. Breaking a SHA-1-generated SSH authentication key now costs roughly $50,000, putting high-profile remote servers at risk of attacks.
