What Is a SHA-1 Hash?

SHA-1 is a cryptographic hash function that converts any input text into a fixed 40-character hexadecimal string (160 bits). Like other hash functions, the same input always produces the same output, and any change to the input changes the hash completely.

SHA-1 was widely used for digital signatures and certificates but is now considered weak against determined attackers and has been phased out in favor of SHA-256 for security-sensitive uses — it still remains common for non-security checksums and version-control systems like Git.

İpuçları

Avoid SHA-1 for New Security Systems

For new security-sensitive work, prefer SHA-256 or SHA-512 instead.

Use It to Match Git Commit Hashes

Git historically uses SHA-1 for commit identifiers, which this tool can help you understand.

Sıkça Sorulan Sorular

No — SHA-1 is considered weak against determined attackers for security-critical uses like certificates, though it remains common for non-security checksums.

SHA-1 always produces a 160-bit hash, represented as 40 hexadecimal characters, regardless of input length.

Yes — Git historically identifies commits using SHA-1 hashes, though newer Git versions support SHA-256 as well.

No — hashing uses your browser's built-in Web Crypto API and never leaves your device.

Not directly — hashing is one-way by design.

Use SHA-256 or SHA-512 for new security-sensitive applications.
