Decryption Test Utility (1024-bit)

This test decryptor utility is developed to assist Registrars in decrypting the Registrar Enrolment Packets before go-live. This utility works with packets that are encrypted with 1024-bit key (see below for 2048-bit key tool)This utility supports only PFX and PEM formats for private key files. The private key files must be password protected. This tool also supports USB Token with .Net PKCS11 APIs at location "C:\WINDOWS\system32\aetpkss1.dll".

For all the other cases, a modification in the source code of Decryptor Utility is necessary for execution the decryption. Full source code is available below for download.

This is designed purely as a test tool along with source code provided for initial testing. THIS IS NOT A SUPPORTED SOFTWARE.
