I have a self-signed certificate(not popular X.509 one). The certificate and ECDSA public/private key pair are generated by java program using bouncy castle. I need to verify this certificate with C program using openssl. However, the ECDSA signature can be verified by java program correctly, but failed with openssl verification. banks, stock markets, governments, police forces – Cryptographic Security of ECDSA in Bitcoin P vs. NP • If you solve P vs. NP it: 1 M$. • Nobel price, Abel price in mathematics: roughly 1M$ TLS, OpenSSL ever used??? Y 98.3% of EC U.S. ANSI X9.63 for Financial Services Y Y NSA suite B, NATO military crypto Y It is well known that ECDSA is very vulnerable to weak RNGs to generate the secret nonce, and we’ve wanted to use deterministic signing (RFC6979) in Bitcoin Core for a long time. However, Bitcoin Core currently relies on OpenSSL for ECDSA operations, and changing this is very nontrivial due to consensus risk. You can check the known OpenSSL PEM types by looking in the openssl pem header file (include/openssl/pem.h). You will notice that there is no "EC PUBLIC KEY" entry. There is an "RSA PUBLIC KEY", "DSA PUBLIC KEY" and "ECDSA PUBLIC KEY", but the latter two are not used anywhere in the OpenSSL codebase (i.e. they only exist in the header file). Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts. It only takes a minute to sign up. Signing a raw transaction with Python ECDSA (or OpenSSL) Ask Question Asked 5 years, 3 months ago. and then signed with an ECDSA library.
