Best Encryption Software for Mac and Why Should You Use It?

Encryption plays an important role in data protection. Encryption software helps to keep our personal data safe. An encrypted data can be decrypted and read only by the user who has the password. Unencrypted data is termed as plain text whereas encrypted data is known as cipher text. The market is flooded with encryption software’s but not all software’s are good enough. After a lot of research and market evaluation we bring to you the best encryption software for Mac: Gnu PRIVACY GUARD.

About Gnu Privacy Guard

Commonly abbreviated as GnuPG, the software is a hybrid-encryption because of the combined use of symmetric-key cryptography for speed and public-key cryptography for easy and secured key exchange. The recipient’s public key is used only once to encrypt a session key. It is free software that implements the OpenPGP, allowing you to encrypt and sign your data and communication. GnuPG has an adaptable key management system and access modules for all types of public key directories.

Working of GnuPG

The software encrypts the messages using asymmetric keypairs which are individually generated by its users. The ensuing public keys can be exchanged with other users in many ways, like internet key servers. The keys must be carefully exchanged to avoid spoofing of identity; it can be done by corrupting the public key. A digital signature can be added so the sender and integrity of the message can be verified. GnuPG avoids the usage of any restricted software’s or patented algorithms, using a various other, non-patented algorithms.

There are 3 actively maintained branches of GnuPG:

  • 2.0.29 which is the stable version and is suggested for most users.
  • 2.1.11 is the new modern version with support for ECC and many new features.
  • 1.4.20 is the classic version, suitable for older platforms.

You cannot install the modern and stable version together; however either of them can be installed with the classic version.
