The SHA-1 algorithm, one of the first widely used methods of protecting electronic information, has reached the end of its useful life, according to security experts at the National Institute of ...

Security experts are warning that a security flaw has been found in a popular and powerful data encryption algorithm, dubbed SHA-1, by a team of scientists from Shandong University in China. The three ...

The US National Institute of Standards and Technology (NIST) has announced the phasing out of the secure hash algorithm (SHA)-1 in the federal government. The agency said it will stop using SHA-1 in ...

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 ...

it isn't spelled out like in later algorithms but the plain "rsa" option here is an implicit rsa with sha-1 hashes. on edit: this hasn't been true for some time. Sorry for the confusion. Today -t rsa ...

Abstract: Challenge-and-response authentication requires a MAC originator and a MAC recipient to compute a message authentication code based on a hidden secret and public data. The originator is ...
