python 使用OpenSSL生成RSA密钥对

Posted 2021-05-09

#openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048
#openssl rsa -pubout -in private_key.pem -out public_key.pem

import OpenSSL
pkey = OpenSSL.crypto.PKey()
pkey.generate_key(OpenSSL.crypto.TYPE_RSA, 2048)
print(OpenSSL.crypto.dump_privatekey(type=OpenSSL.crypto.FILETYPE_PEM, pkey=pkey))
print(OpenSSL.crypto.dump_publickey(type=OpenSSL.crypto.FILETYPE_PEM, pkey=pkey))
