X.509 / SSL Certificate Decoder

Hash Generator

Compute hashes of text or a file with thirteen algorithms at once: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160, BLAKE2b, BLAKE2s, BLAKE3, CRC32, and Adler-32.

Checksum Verifier

Verify the integrity of a file or text — paste the expected hash and the tool will detect the algorithm among 13 supported ones.

HMAC Generator

Compute HMAC (Hash-based Message Authentication Code) of text or a file with a secret key — eight algorithms at once: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160.

Bcrypt Hash + Verify

Hash passwords with bcrypt (random salt, adjustable cost) and verify a password against an existing bcrypt hash.

UUID Generator

Generate UUID versions 1, 3, 4, 5, 6 and 7 — random, time-based, and name-based.

Password Generator

Cryptographically random passwords with configurable length and character set.

Data URI / Base64 image

Encode an image into a Data URI (data:image/…;base64,…) for embedding in CSS/HTML, and decode a Data URI or raw Base64 back into a file — all in your browser.

Number Base Converter

Convert between binary, octal, decimal, hexadecimal, and any arbitrary (2-36) base — enter a number into any field.

Mock JSON Generator

Generate fake JSON data from a template: placeholder values like {{name}} or {{email}}, and arrays repeated via "key|N".

Sort & Dedupe Lines

Sort lines of text alphabetically, remove duplicates, empty lines, and extra whitespace.

HTML Minify / Beautify

Compress HTML for production, or format minified markup into a readable layout.

Punycode encode/decode

Encode internationalized domain names (IDN) with unicode characters into ASCII-compatible Punycode (xn--) and back.
