Hash Generator
Generate MD5, SHA1, SHA256, SHA512 hashes
About Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text input. Hash functions are one-way functions commonly used for data integrity verification, password storage, and digital signatures.
Frequently Asked Questions
Which hash algorithm should I use?▼
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered cryptographically broken and should only be used for checksums, not security.
Can hashes be reversed?▼
No, cryptographic hash functions are one-way functions. You cannot derive the original input from a hash value. This is by design.
Why do different inputs sometimes produce the same hash?▼
This is called a collision. While theoretically possible for any hash function, modern algorithms like SHA-256 make collisions practically impossible to find.
