SHA1 Generator
Generate SHA1 and other cryptographic hashes from text
Note: SHA1 is considered cryptographically broken for security purposes. Use SHA256 or SHA512 for security-critical applications.

What is Hashing?
Hashing converts input data into a fixed-length string of characters. It's a one-way function - you can't reverse a hash to get the original data. Commonly used for password storage, data integrity verification, and digital signatures.
Common Uses
- ✓ Password storage (with salt)
- ✓ File integrity verification
- ✓ Digital signatures
- ✓ Data deduplication
- ✓ Checksums for downloads
