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.
Fast and easy from start to finish
Paste text or switch to the file tab and select a file.
Choose display case; optionally enter an HMAC key for text.
Copy the needed hash and compare it with the expected value.
What you can do with this tool
Text hashes: Calculate the available MD5 and SHA results as text changes.
Keyed text hash: Enter a key for HMAC-SHA-256.
File checksums: Calculate SHA-256 and SHA-512 from the selected file.
Copy formatting: Copy a result and choose uppercase or lowercase display.
Everyday walkthroughs and starter ideas for Cryptographic Hash Generator
Hash the same sentence with and without a final newline and compare the results.
File requirements, capabilities, and system limits
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.
Helpful definitions of features and parameters
A fingerprint you compare with a trusted value to check whether a file's bytes match.
How creators, students, and professionals use Cryptographic Hash Generator
Compare a download with a trusted SHA-256 checksum.
Check whether two text inputs produce the same fingerprint.
Answers to common questions about Cryptographic Hash Generator
A hash is a fingerprint rather than reversible encoding. This tool does not decrypt or decode hashes.
No. It computes hashes from the input without checking whether the text is valid code.
Use SHA-256 or SHA-512. The current file-MD5 implementation reads only an initial portion of large files, so it should not be used to verify the whole file.
