Crypto key generate rsa modulus 1024 or 2048
WebWhen you use the crypto key generate rsa command, it will ask you how many bits you want to use for the key size. How much should you pick? It’s best to check the next generation encryption article from Cisco for this. At this moment, a key size of 2048 bits is acceptable. Key sizes of 1024 or smaller should be avoided. Webfprintf(stderr, "Could not open private key file %s\n", priv_key_file); exit(1); // openssl has this handy function to write out our private key in the correct format.
