-----------------------------------
To create a new public key, size 2048 bits:
-$ openssl genrsa -F4 -out keys/dev.key 2048
+$ openssl genpkey -algorithm RSA -out keys/dev.key \
+ -pkeyopt rsa_keygen_bits:2048 -pkeyopt rsa_keygen_pubexp:65537
To create a certificate for this:
- rsa,num-bits: Number of key bits (e.g. 2048)
- rsa,modulus: Modulus (N) as a big-endian multi-word integer
+- rsa,exponent: Public exponent (E) as a 64 bit unsigned integer
- rsa,r-squared: (2^num-bits)^2 as a big-endian multi-word integer
- rsa,n0-inverse: -1 / modulus[0] mod 2^32
