PGP/GPG Encrypt/Decrypt

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.

IEEE 754 Float Converter

Decimal number ↔ IEEE 754 binary representation (single or double precision) — sign, exponent, mantissa, special values.

Query String ↔ JSON

Parse a URL query string into a JSON object, or build a query string back from JSON.

JSONPath Tester

Test JSONPath expressions against real JSON data — instantly see the matched values and their paths.

Barcode Generator

Generate a linear barcode (CODE128, EAN-13, UPC, CODE39, and others) from text or digits.

Unix Timestamp ↔ Date

Convert Unix time to a date and back, with support for arbitrary (IANA) time zones.

Cron Parser

Parse a cron expression (5 or 6 fields, including @-shortcuts) — a plain-language schedule description and next run times in a chosen time zone.
