SHA1 Hash Generator

SHA1 was traditionally used for SSL certificates and data integrity. Today, it remains a standard in version control systems like Git to uniquely identify file changes and commit history objects effectively.

SHA1 is theoretically vulnerable to collision attacks where two different inputs produce the same hash. Most security experts recommend transitioning to SHA-256 for critical security applications and modern digital signatures.

A SHA1 hash always produces a fixed-length output of 160 bits. When represented in a hexadecimal format, it appears as a unique string of 40 characters containing numbers and letters (a-f).
