SA5Reader is a freely downloadable, decrypt-only version of SecretAgent 5. It allows you to open any archive that was encrypted for you by a SecretAgent 5 user by simply entering your password and clicking Decrypt. All you need to supply is the PKCS#12 private key file (or SA5 .prv file) corresponding to your X.509 certificate.

The latest SA5Reader release is compatible with SecretAgent 5.7. It consists of a portable Java-based user interface layered over a JNI cryptographic library based on our FIPS 140-1 certified CDK 7.0.

NOTE: SA5Reader cannot generate keys or certificate requests, encrypt files, validate digital signatures, or handle CMS or OpenPGP file formats. For those additional features, you'll need to license a copy of the full SecretAgent 5.7 for your particular platform.

To decrypt a file:

1) Start SA5Reader and select the .sa5 file you wish to decrypt.

The changing graphic at the top of this dialog is simply advertising... ignore it, or click on it to visit a web page containing more information about the advertised item.

2) Complete the rest of the form. If desired, you may modify the Output folder (the target directory for plaintext files), the file specification for your Decryption key (a .p12, .pfx, or SA5 .prv file), and the Overwrite files setting. Your preferences for these items will be remembered when you exit the program.

3) Enter the Password for your private key and then click Decrypt.

4) When decryption is complete, a list of the plaintext contents of the archive will appear in a Decryption Status dialog. You can double click on any filename in that list to open that file in the appropriate Macintosh application. When done, close the Status dialog.

5) Click Exit to terminate the SA5Reader application.
