#️⃣ Hash

Hash text or files, and verify a download’s checksum. MD5, SHA-1/2/3, Keccak, BLAKE2/3 and RIPEMD-160.

Notes

Keccak-256 is the original Keccak used by Ethereum; SHA3-256 is the NIST standard with different padding, so their outputs differ. MD5 and SHA-1 are broken for collision resistance; use them only to check old checksums. Files are hashed in 4 MB chunks, so large files work without loading them into memory.
