Text Hash Generator
Create SHA-1, SHA-256, SHA-384, or SHA-512 digests from UTF-8 text and display the result as hexadecimal, Base64, or Base64URL.
Use Tool →File Checksum Generator
Calculate SHA checksums for local files without uploading the file, with hexadecimal, Base64, and Base64URL output options.
Use Tool →Checksum Verifier
Compare an expected SHA checksum with a locally calculated checksum from text or a selected file and report an exact match or mismatch.
Use Tool →HMAC Generator
Generate keyed HMAC authentication codes using SHA-256, SHA-384, or SHA-512 with UTF-8, hexadecimal, or Base64 key input.
Use Tool →Subresource Integrity Hash Generator
Generate SHA-256, SHA-384, and SHA-512 Subresource Integrity values from a local file or pasted resource content.
