This is a small tool for quickly encrypt your message by RSA into the Base64 form, so that you can paste it to anywhere you want to avoid information leak etc.

• Mac OS supported curretly.
• openssl

Generate key file.

openssl genrsa -out mykey.pem 1024  

Extract public key from key file.

openssl rsa -in mykey.pem -pubout -out pubkey.pem  

sh encrypt.sh "Your message is here" 

The message you enter will encrypt by your public key (pubkey.pem), and then transform to base64 form, finally copy to your clipboard automatically. Then you can copy this to anywhere you want, eg. in email text or in any note app.

sh decrypt.sh b9ZiPUB1VIQgzP0QWz7Z1Gbk/NaWqi58T0vQLo2C4+SYuyYfdpB0dyy4pyXnIDTokqA2x3ozbqDX0eMYRJer3RccvzHa3B0coYKEd6c9+67Z2Bnm5M7Ss5Jmi+OjHmP7zMKrl7ejuTeF9NzY6EhEoJmcgLFReM1+7ZvXhLuvrRc=

You should replace the base64 string above with your own encrypted message. Then you can see the original message (plain text), and it will also copy to your clipboard simultaneously.
