About SHA-1

SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function that produces a 160-bit (20-byte) hash value, typically expressed as a 40-character hexadecimal number.

Note: SHA-1 is considered cryptographically broken and should not be used for security-sensitive applications. Use SHA-256 or SHA-512 instead.

Use cases: Legacy system compatibility, checksums for non-security purposes, and data integrity verification in low-risk scenarios.
