Secure Parcel Delivery version 1.2 brings a number of long-awaited improvements.

• Switching to the latest and greatest Cryptographic Service Provider (CSP)
  • Microsoft Enhanced RSA and AES Cryptographic Provider
  • Valid for Windows XP and later
• Adding the Advanced Encryption Standard (AES) symmetric cipher to the fold
• Restricting symmetric encryption ciphers and key strengths to those allowed by FIPS 140-2 (and FIPS 140-3)
  • See http://en.wikipedia.org/wiki/FIPS_140-2
  • Allowed ciphers include triple DES and AES with a minimum key length of 128 bits
  • Disabling selection of RC4, RC2, DES, 2-key 3DES
• Allowing user selection of RSA key size from 1024 to 16384 bits in 256 bit steps
  • I suggest you take the default RSA key size of 3072 bits
  • FIPS 140-3 will require at least 3072 bits (to set a minimum cryptographic strength of 128 bits overall) but the program will let you choose keys down to 1024 bits at this time
• Consolidation of User and Key interface elements to simplify configuration

This version is 32-bit only and tested on:

• Windows 7 Professional x64
• Windows Vista Business x86
• Windows XP SP3 x86

Cheers!
