It is a slightly … WebNov 4, 2016 · SHA-1 is not generally broken for every kind of use case. But, it is considered that it provides insufficient protection against collision attacks which makes it unsuitable as a signature algorithm for example in certificates. It still is secure enough for use in HMAC though which is similar (but not equal) to your use case.

WebWould you use HMAC-SHA1 or HMAC-SHA256 for message authentication? Yes. That is a semi-serious answer; both are very good choices, assuming, of course, that a Message Authentication Code is the appropriate solution (that is, both sides share a secret key), and you don't need extreme speed. How much HMAC-SHA256 is slower than HMAC-SHA1?
