Hash Generator — MD5, SHA-256, SHA-512
Calculate hashes for text or files. Generate MD5, SHA-1, SHA-256, or SHA-512 output, switch casing when needed, and copy the hash for comparison.

How to Generate Hashes
- Choose input type — Select Text Input to hash a string or File Input to hash any file.
- Enter your data — Type or paste text in Text mode, or drop a file in File mode. Hashes generate automatically.
- Copy your hash — Click the Copy button next to any hash algorithm to copy it to clipboard.

Hash generator for text and files
Use Hash Generator to calculate MD5, SHA-1, SHA-256, and SHA-512 values for text or a selected file. Hashes can compare equality or detect changes, but they do not encrypt data.
Example workflow
- Checksum comparison: Drop a downloaded file into File Input, generate SHA-256, and compare it with the checksum published by the source.
- Text comparison: Paste a string in Text Input and copy the hash needed by another system.
- Limits: MD5 should not be used for security-sensitive integrity checks, and a matching hash does not prove content is trustworthy.

Frequently Asked Questions
What is a hash function?
A hash function turns input data into a fixed-length value. Matching hashes can help compare two inputs, but a hash is not encryption.
What is SHA-256 used for?
SHA-256 is commonly used for checksum and integrity comparisons. For example, compare a downloaded file's SHA-256 with the checksum published by the source.
Is MD5 secure?
No. MD5 is considered broken for security-sensitive use. Prefer SHA-256 or SHA-512 for modern integrity checks.
Can I hash files as well as text?
Yes. Text mode hashes typed or pasted text, and File Input mode reads a selected file and generates hash values.
Can hashes prove a file is safe?
No. A matching hash can show that two copies are the same, but it does not prove the content is trustworthy or malware-free.
