using openssl rsa to encrypt and decrypt text file

opensslRSA

using openssl rsa to encrypt and decrypt file, current only support key size of 2048, and only support pem key

1. rsa only support text file
2. rsa_base64 can support binary file encrypt/decrypt.

• The encrypt procedure: file->base64->rsa
• The decrypt procedure: file->rsa->base64

Dependency

The openssl rsa depende on base64, if the file is unicode/binary file, use base64 to encode the string

Usage

You can use python pycrypto.py to generate pem key, and for the detail usage use rsa -h.

 cd base64 && make
 make
 rsa -h
 rsa -i input -o cypher -k pubkey // encrypt a text file
 rsa -d -i cypher -o output -k prikey // decrypt a text file
 python pycrypto.py

 rsa_base64 -i input -o cypher -k pubkey // encrypt a text file
 rsa_base64 -d -i cypher -o output -k prikey // decrypt a text file
