1 | ## @file\r |
2 | # This tool can be used to generate new RSA 2048 bit private/public key pairs \r | |
3 | # in a PEM file format using OpenSSL command line utilities that are installed \r | |
4 | # on the path specified by the system environment variable OPENSSL_PATH.\r | |
5 | # This tool can also optionally write one or more SHA 256 hashes of 2048 bit \r | |
6 | # public keys to a binary file, write one or more SHA 256 hashes of 2048 bit \r | |
7 | # public keys to a file in a C structure format, and in verbose mode display \r | |
8 | # one or more SHA 256 hashes of 2048 bit public keys in a C structure format \r | |
9 | # on STDOUT.\r | |
10 | # This tool has been tested with OpenSSL 1.0.1e 11 Feb 2013\r | |
