A private key is a randomly generated number. A Private Key But to be more exact, because bitcoin uses 256-bit numbers, a randomly generated private key starts out looking like this. There is an additional 0x01 suffix byte at the end (just before the 4 checksum bytes) which indicate that the public key associated with this private key is to be generated in compressed form (33 bytes) rather than uncompressed form (65 bytes).
