ECDSA (‘Elliptical Curve Digital Signature Algorithm’) is the cryptography behind private and public keys used in Bitcoin. It consists of combining the math behind finite fields and elliptic ... An example private key. In Bitcoin, a private key is a 256-bit number, which can be represented one of several ways. Here is a private key in hexadecimal - 256 bits in hexadecimal is 32 bytes, or 64 characters in the range 0-9 or A-F. Michael Brengel and Christian Rossow's Identifying Key Leakage of Bitcoin Users (in proceedings of RAID 2018) is an interesting attack against bitcoin implementations.It gives a good illustration that nonce must be generated with great care in ECDSA (and other DLog-based signature schemes).
