What is Hash Generator?
A hash generator creates fixed-length cryptographic digests from any text input using algorithms like MD5, SHA-1, SHA-256, and SHA-512. Hashing is used for password storage, data integrity verification, file checksums, and digital signatures.
How to Use
- Enter or paste the text you want to hash
- Select one or more hash algorithms (MD5, SHA-1, SHA-256, etc.)
- View the hash output for each algorithm instantly
- Copy any hash value with a single click
Frequently Asked Questions
- Which hash algorithm should I use?
- SHA-256 is the current standard for most purposes. MD5 and SHA-1 are considered broken for security but still useful for non-security checksums.
- Can a hash be reversed to get the original text?
- No, hashing is a one-way function. You cannot mathematically reverse it. However, common inputs can be found using rainbow tables, which is why salting is important.
- What is the difference between hashing and encryption?
- Hashing is one-way and produces a fixed-length output. Encryption is two-way -- you can decrypt with the correct key. Use hashing for verification, encryption for confidentiality.
