+  ssh-keygen -f ~/.ssh/id_rsa.pub -e -m pkcs8 > /tmp/id_rsa.pub.pem
+
+
+OpenSSL operations
+==================
+
+  * Encryption:
+
+  openssl rsautl -encrypt -pubin -inkey /tmp/id_rsa.pub.pem > /tmp/c.txt
+
+  * Decryption:
+
+  openssl rsautl -decrypt -inkey ~/.ssh/id_rsa -in /tmp/c.txt
+
+  * Signing:
+
+  openssl dgst -sha1 -sign ~/.ssh/id_rsa file.txt > file.txt.sig
+
+  * Verification:
+
+  openssl dgst -sha1 -verify /tmp/id_rsa.pub.pem -signature file.txt.sig file.txt
