Notes: In general, it may be necessary to convert s to 'Low S' form but in this case PGP made it that way already. Then download the files. Compute the digest according to the selected hash type,.g.: digest SHA256(msg). The 'hashed part' and then six more bytes get appended to the signed data: msg 48656c6c6f20776f726c64210a e0c5180 04ff0000000c. Dat, yielding the following detached signature file: 885e e0c5180 000a0910 2d91cad9873ecc6a 4f3c00fe 82b4 00ff 6eaa a2ba9eb a81479e5f32e8f9bce bacc07062616 Here I have highlighted four important parts: The signature 'hashed part' which includes pubkey algorithm-id 0x 13 (ecdsa hash algorithm-id 0x 08 (SHA256) and the signature creation.

The latest binaries and signed hash files can be found on the releases page or on the github releases page. 2b8104000a is an OID indicating the curve is secp256k1. Extract the signature data - the (r,s) multiprecision integers - and convert it to the bitcoin DER representation. If Bob stops responding then Alice can recover her funds with just the stack (tx_sig, 1) -.e., the transaction is just signed by her key alice_bitcoin_pubkey. Includes a python script that extracts PGP data and creates a bitcoin transaction. Format in order to get pubkey. Do stuff based on checkdatasig result (items in parentheses show the stack state after performing the operation) Note however this means a PGP signature from the oracle on any message starting with "Broncos win!
