128-bit) you want to use for your encryption keyД«ut in order for your recipient (Bob in this case) to know how to decrypt the cipher youвЂ™ve sent to them, they also need to know the key youвЂ™ve used. This is why, when generating keys, youвЂ™ll typically be asked to provide the key size (e.g. Note: the longer the key, the more secure the encryption will be. A key can be used to both encrypt and decrypt plaintext. A key is a mathematical algorithm for turning plaintext into seemingly random alphanumeric characters. In order to encrypt the plaintext into a cipher we need to use a technique that relies on the concept of a вЂњkeyвЂќ.

#GPG SUITE HOW TO PASSWORD#

To prevent this devious person from being able to see the password we would need to encrypt the plaintext document into a cipher and to transfer the cipher instead of the plaintext, meaning if anyone was to interrupt your communication then they would get the cipher and it would be unreadable. But this isnвЂ™t very safe because you could have some devious person вЂsniffingвЂ™ your network traffic, picking up your communication and subsequently stealing the plaintext file containing the password youвЂ™d rather they not get access to. You could open an email (or chat program), attach the file and send it to Bob. Imagine you have a plaintext file which contains a password, and you want to share this file with someone else across the internet (letвЂ™s say this someone is our friend вЂњBobвЂќ). When a file is said to be plaintext it simply means that itвЂ™s unencrypted, whereas a cipher is a noun that refers to a plaintext that has been encrypted. ItвЂ™s important to know what these mean before moving on, so letвЂ™s clarify this now: Throughout this post youвЂ™ll see me use words like вЂњplaintextвЂќ and вЂњcipherвЂќ. ItвЂ™s taken me longer than I care to admit to really understand the things IвЂ™ll be discussing here (and even then IвЂ™ll likely have missed a lot of important nuances), and with that said: what am I planning on covering in this post? Well that would beвЂ¦

Helping others to also understand the purposes of said tools.

Solidify my own understanding of the tools IвЂ™ll be covering.

Now the actual purpose of this post was twofold: Note: although quite a tough read at times, I would highly recommend вЂњBulletproof SSL and TLSвЂќ written by Ivan RistiД‡ If youвЂ™re working with applications and/or servers in production then please consult someone better equipped on the subject of security. IвЂ™m not even a security intermediate! When I titled this post вЂњsecurity basicsвЂќ I wasnвЂ™t kidding. This post isnвЂ™t meant to be вЂњthis is how you do securityвЂќ. Just skip until What is GPG? (in there are two sub sections about вЂњOpenSSHвЂќ, вЂњSSH AgentвЂќ and вЂњOpenSSLвЂќ, just skip those until you get to the next вЂњGPGвЂќ section and continue all the way from there) Introduction UPDATE: for those short on time, read the following Introduction, What are keys and how do they work? and then skip over the sections вЂњUnderstanding PKIвЂќ and вЂњOpenSSL vs OpenSSHвЂќ as these just go into more depth on the technical aspect of different encryption concepts.

Creating, self-signing, issuing and revoking certificates.

How to encrypt data using GPG, OpenSSL and Keybase.

Hit enter and you will be asked for you password.

Type gpg -d(mind the space after -d) and drag the file into the terminal. Open Spotlight and type 'Terminal.app'(or open a Finder > Applications > Utilities > Terminal.app) and click on it. To decrypt the file you can also use a Terminal.

#GPG SUITE HOW TO INSTALL#

In this case install the GPG Suite again. If you can't find GPGServices you may have a corrupted or old installation. Click CMD+ Shift+ G and type /Library/Services.Д¬hose rvice, change for all and close the Info window. If you click and hold the drop down menu, chose 'Other. Now you can chose a application with which the file should be open with. To manually assign the file extension to a application or service click on the myfile.gpg and then CMD+ I. The appropiate service is named rvice and can be found in /Library/Services/.

Your Mac should have an association with a *.gpg file.
