常用示例
Generate EC key
openssl ec -in [key.pem] -text -noout
Generate EC private
openssl ecparam -genkey -name [prime256v1] -out [key.pem]
Convert EC key
openssl ec -in [key.pem] -outform DER -out [key.der]
说明
openssl ec handles Elliptic Curve (EC) key operations including reading, writing, and converting EC private keys. EC cryptography provides strong security with smaller key sizes compared to RSA. The command reads EC keys in various formats and can output them in PEM or DER encoding. It's used for key management in TLS configurations and digital signatures. EC keys are generated using ecparam with a named curve, then processed with the ec command for format conversion or examination.
