- Generate an RSA private key of 2048 bits, saving it to a specific file:
openssl genpkey -algorithm rsa -pkeyopt rsa_keygen_bits:{{2048}} -out {{filename.key}}
- Generate an elliptic curve private key using the curve
prime256v1, saving it to a specific file:
openssl genpkey -algorithm EC -pkeyopt ec_paramgen_curve:{{prime256v1}} -out {{filename.key}}
- Generate an
ED25519elliptic curve private key, saving it to a specific file:
openssl genpkey -algorithm {{ED25519}} -out {{filename.key}}
