SHA1 Hash Generator

Generate SHA1 (Secure Hash Algorithm 1) hashes from text. Note that SHA1 is a 160-bit hash function that is no longer considered cryptographically secure due to vulnerabilities.

About SHA1 Hash

Hash functions convert input data into fixed-size output strings
Each algorithm produces different length outputs and has different characteristics
MD5 (128-bit) and SHA1 (160-bit) are older and no longer considered cryptographically secure
SHA256 and above are currently recommended for security applications
The same input will always produce the same hash output
Even small changes in input produce completely different hashes
