Common questions and answers about this topic.
SHA-1 produces a 160-bit (40-character hex) hash. It was widely used in Git commits and certificates but is now considered weak for cryptographic use.
SHA-1 is deprecated for cryptographic purposes due to known collision attacks. Use SHA-256 or SHA-3 for security-critical applications.
No, hash functions are one-way.
No, SHA-1 hashing runs entirely in your browser. Your input data is hashed locally with JavaScript and never sent to any external service.
