Shift letters with a ROT offset, or brute-force all 26 rotations to spot plaintext.
Compute MD5, SHA-1, SHA-256, and SHA-512 digests for a local file — entirely in your browser, nothing is uploaded.
Guess the hashing algorithm behind a digest from its length, charset, and prefix.
Compare hashes, inspect digests, and validate checksum integrity for software, files, and string values.
Build keyed signatures and verify message authenticity using common HMAC algorithms.
Generate quick, high-entropy passwords with a customisable length.
Encode or decode Base64 strings instantly.
Switch a value across decimal, binary, octal, and hexadecimal representations.
Escape or unescape HTML entities to prevent injection and render text safely.
Encode or decode URL components safely while preserving format.
XOR data byte-by-byte with a repeating key. Symmetric — the same output, pasted back, restores the original.

Validate a hardware MAC address, normalize its formatting, identify the OUI vendor, and generate random addresses.
Simulate a quick service sweep against a target to review common open ports.
Review CIDR ranges, subnet masks, network blocks, and usable host counts.
Compare two text blocks line by line with a longest-common-subsequence diff and see exactly what changed.
Detect look-alike Unicode characters and invisible zero-width markers that are used to spoof domains and text.
Test a regular expression against sample input and review every match inline.
Inspect characters, byte sizes, composition, and entropy of any string.
Convert Unix timestamps into ISO, UTC, and local human-readable values.
Break any URL into scheme, host, port, path, query parameters, and fragment — and flag embedded credentials.
