The .aex file extension is commonly used in files associated with Pretty Good Privacy (PGP) encryption application for Microsoft
Windows. Files with .aex extension are identified as encoded encryption files that are used to protect the users' communications,
emails, files, directories, and whole disk partitions. It also contains the protocols for data authentication and security analysis.
AEX files are also used in some security software to detect anomalies and viruses from incoming electronic communications.
PGP or Pretty Good Program is a program that uses a fast encryption algorithm which is utilized to encrypt and decrypt email over the
Internet. It also serves as a software that authenticates messages with digital signatures and encrypted stored files. PGP also uses
public key systems to generate .aex files. This system requires each user an encryption key that is publicly known and a private key
that is known only to the user. The user can encrypt a message before sending it to someone using their public key. When the other
user receives the message, he can decrypt it using his own private key.
