Compute MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes online instantly with real-time updates.
Create digital fingerprints of text and files. The text workspace calculates MD5 and SHA hashes, with an optional HMAC key. For file verification, use the SHA-256 or SHA-512 result and compare it with a trusted checksum. Hashing is not syntax validation or encryption.
Step-by-Step Walkthrough
Step 1
Paste text or switch to the file tab and select a file.
Step 2
Choose display case; optionally enter an HMAC key for text.
Step 3
Copy the needed hash and compare it with the expected value.
Pro Tip for Best Output Quality
MD5 and SHA-1 are not appropriate choices for security-sensitive collision resistance.
File MD5 is limited for large files. This tool is not a password-storage system.
