Hash Functions
This tool computes the SHA256, Hash256, RIPEMD160, and Hash160 of a given input
Bitcoin Hash Functions
Select a hash function and enter a hex value to compute its hash
SHA256
Single SHA256 hash, foundational cryptographic hash function used widely in Bitcoin processes.
Used in Bitcoin for:
- First step in Hash256 (double-SHA256)
- Checksum calculation in BIP39 mnemonic generation
- Tagged hashes in Taproot (BIP340/BIP341)
Double SHA256 (Hash256)
Double SHA256 (SHA256 applied twice), standard Bitcoin hashing method for IDs and proofs.
Used in Bitcoin for:
- Block hash calculation
- Transaction ID (txid) generation
- Merkle tree node hashing
- Proof-of-Work mining
RIPEMD160
RIPEMD160 hash function, used in combination with SHA256 for creating shorter addresses.
Used in Bitcoin for:
- Second step in Hash160 (SHA256 + RIPEMD160)
- Used after SHA256 in public key hashing
- Ensures shorter, fixed-length address representation
Hash160 (SHA256 + RIPEMD160)
SHA256 followed by RIPEMD160, standard method to hash public keys and scripts for Bitcoin addresses.
Used in Bitcoin for:
- P2PKH address generation
- P2SH script hash calculation
- P2WPKH (SegWit) witness program
