About SHA-1

SHA-1 (Secure Hash Algorithm 1) produces a 160-bit (20-byte) hash value, typically expressed as a 40-character hexadecimal number. While stronger than MD5, SHA-1 is considered cryptographically weak and should not be used for security-sensitive applications. It is still used in some legacy systems and for non-security purposes like Git commit hashes.
