htlc calc-secret-hash

Legacy spelling: this command was previously spelled htlc-calc-secret-hash. Both spellings work, but only the nested spelling shown here appears in help and tab completion (v1.4.5+).

Calculate the hash of a given HTLC secret.

Usage

htlc calc-secret-hash <SECRET>

Arguments

• <SECRET>: The hex-encoded HTLC secret to hash.

Notes

The resulting hash is what you provide to htlc create when setting up the HTLC. The secret itself is kept off-chain and revealed only when spending the HTLC.
