You have chosen a sufficiently random, high entropy password to be resilient against brute force attack.Really, for all practical purposes that means the data is encrypted with a password that you choose! The challenge then is two-fold: Whereas in the more powerful asymmetric mode, two related keys are used for encryption and then decryption of a message, in symmetric mode the same key is used for both encryption and decryption. Basically, with these cards your private key is stored off your computer on the smart card that cannot be copied and is protected with a minimum 6 digit PIN. One of my cards is pictured in the photo above. I have several of these here in the Rietta office, and I will be sure to release a post about them in the future. There is an OpenPGP Smart Card that uses Chip & PIN technology to protect the private key so that it is not stored on your general computer. The password decrypts the key, that in turn decrypts the asymmetrically encrypted message that you want to open. When you go to sign a message or decrypt a message that you have received, your computer prompts you for your password that locks the private key material. The normal mechanism for storing your private key is in a file on your computer that is protected by a passphrase, so it takes something you have (the key file) and something you know (the password) to decrypt messages or data that is encrypted to your associated public key. My OpenPGP public key since 2003 is 0x1F9016AF. The Wikipedia article on public-key cryptography is a good place to start to read up on the foundation. The most famous, and useful, is public key crypto where each user has his or her own private key that is kept confidential and the public key that is shared with anyone who needs to send encrypted messages. OpenPGP Encryption Modes Asymmetric Mode ( Key Pairs) Generally it is thought of as an e-mail encryption system, but its uses include protecting backups, storing secrets in your Git repository, and it is supported in major SQL database servers - such as in PostgreSQL. It is a technology that lets you encrypt files and messages.

Encryption software is a significantly important tool for protecting the confidentiality of information on the internet, from prying eyes - both private parties and various governmental agencies. I like the GNU Privacy Guard (GPG) because it’s GNU Privacy Guard (GnuPG or GPG) is a GPL alternative to the PGP suite of cryptographic software. I’ve been a user of PGP and GnuPG for over a decade. If this is new to you, this fun challenge will help you get started with what you need to decrypt a message with GnuPG! If you have been following the news in light of the revelations of the NSA domestic surveillance program, which is probably unconstitutional in the United States but in practice is being permitted by the courts, then you should know something about the encrypt everything movement and Google’s End-to-End project, which is to add OpenPGP to the Chrome web browser.
