Ethereum Keccak-256 hex digest of input — original Keccak (0x01 padding), not NIST SHA3-256. Used for EVM checksums, event topics and Solidity keccak256.

Compute the SHA-512 hash (hex digest) of an input string. Deterministic cryptographic hashing for checksums and fingerprints.

Structural diff of two JSON values: dotted-path lists of added, removed and changed fields, plus an equal flag. Input JSON strings or objects.

Validate whether an input string is well-formed JSON. Returns a valid flag and a parser error message when invalid.

Compare two semantic version strings. Returns -1, 0 or 1 for less-than, equal or greater-than.

Parse a URL into its components: scheme, host, port, path, query and fragment.

Generate a random RFC 4122 version 4 UUID. Unique identifiers for records, requests and idempotency keys.

EIP-55 mixed-case checksum for a 20-byte EVM (Ethereum/Base) hex address, via Keccak-256. Normalize and verify addresses before a transfer.

Compute the MD5 hash (hex digest) of an input string. Fast, deterministic checksums and legacy fingerprints (not for security-sensitive hashing).

Compute the SHA-1 hash (hex digest) of an input string. Deterministic fingerprints and git-style content identifiers.

Convert a JSON array of objects into CSV text with a header row. Flatten structured data for spreadsheets and exports.

Convert an XML document into an equivalent JSON object. Parse XML feeds, SOAP responses and config into JSON.
