    15   * Encryption:

    16 

    17   openssl rsautl -encrypt -pubin -inkey /tmp/id_rsa.pub.pem > /tmp/c.txt

    18 

    19   * Decryption:

    20 

    21   openssl rsautl -decrypt -inkey ~/.ssh/id_rsa -in /tmp/c.txt

    22 

    23   * Signing:

    24 

    25   openssl dgst -sha1 -sign ~/.ssh/id_rsa file.txt > file.txt.sig

    26 

    27   * Verification:

    28 

    29   openssl dgst -sha1 -verify /tmp/id_rsa.pub.pem -signature file.txt.sig file.txt
