PGP File Encryption

PGP combines some of the best features of modern cryptography, including compression, digital signatures and public key encryption.
Encrypting your data files prior to transmitting them to protect the data as it travels to us.

Public Key Encryption
Public key cryptography is an encryption scheme that uses a pair of keys for encryption: a public key, which encrypts data, and a private key for decryption. To send encrypted data to us, you must download the public key and encrypt the file with that key.

The following steps are necessary to use PGP to encrypt files before sending to ADP:

You are now ready to begin encrypting your data files. Here are some general guidelines:

  • Compression is built into the encryption, so it is not necessary to zip your data files before or after encryption.
  • Issued keys will expire every six months.
  • The current key, available from this Web page, will expire on 07/17/2019. If you are using the previous version of our key, please note that it will expire and stop working on 01/16/2019.
