About Hashes
SHA (Secure Hash Algorithm) is a family of cryptographic hash functions.
Hashes are one-way functions. You cannot retrieve the original text from the hash. They are commonly used for:
- Password storage
- File integrity validation
- Digital signatures
- Blockchain technology
Note on Security
SHA-1 is considered cryptographically broken and should not be used for security-critical applications. Use SHA-256 or higher for sensitive data.
