Compute cryptographic hashes using multiple algorithms. Supports keccak256 (Ethereum), SHA-256, and MD5. Input can be plain text or hex-encoded data.
Algorithm Information:
keccak256: Used by Ethereum for addresses, transaction hashes, and event topics. Produces a 256-bit (32-byte) hash.
SHA-256: Widely used in blockchain (Bitcoin), cryptography, and data integrity. Produces a 256-bit (32-byte) hash.
MD5: Legacy hashing algorithm. Not cryptographically secure but still used for checksums and non-security applications. Produces a 128-bit (16-byte) hash.
