Identification

• A file with the .sec file extension is known as a PGP secret key ring.
  
  

Program

• .Sec files are associated with the use of Pretty Good Privacy, produced by PGP Corporation.
  
  

Function

• When you receive or use a file that has been encrypted using Pretty Good Privacy, the information contained in the .sec file allows the data to be decoded. This enables you to access or read the information in the file.
  
  

Benefits

• Because the codes used to produce the files cannot be decoded without the key, .sec files make it impossible for anyone to open a file you have protected with Pretty Good Privacy.
  
  

Systems

• Pretty Good Privacy and .sec files can be used on both Windows- and Mac OS-based operating systems.
