rsatool calculates RSA (p, q, n, d, e) and RSA-CRT (dP, dQ, qInv) parameters given either two primes (p, q) or modulus and private exponent (n, d).
Resulting parameters are displayed and can optionally be written as an OpenSSL compatible DER or PEM encoded RSA private key.
Supplying modulus and private exponent, PEM output to key.pem:
python rsatool.py -f PEM -o key.pem -n 13826123222358393307 -d 9793706120266356337
Supplying two primes, DER output to key.der:
python rsatool.py -f DER -o key.der -p 4184799299 -q 3303891593
