Hi All,

We have an problem our custom CSP using Smart Card for Outlook 2010 ( 64 bit).

1. Problem: Custom CSP using Smart Card for Outlook 2010

We try to decrypt the email the AES algorithm is not working for outlook 2010 email.

The error message appearing: "Your digital ID name cannot be found by the underlying security system"

2. Import your Digital Certificate from a Stored .PFX file

When we are using (import into the machine manually) the .PFX file of our certificate from the local machine without Smart card. The AES options are appearing in the outlook 2010 s/MIME security option in the trusted settings. The AES decryption for s/mime email is working and can decrypt the email.

Also CSP's capabilities by Outlook (Using the 'CryptGetProvParam' function) returning the following:

Supported Algorithms: "ALG_ID | Short Name | Long Name | Min Len | Max Len" 0x6603: 3DES, Three Key Triple DES, 168, 168 0xA400: RSA_KEYX, RSA Key Exchange, 1024, 4096 0x2400: RSA_SIGN, RSA Signature, 1024, 4096 0x8004: SHA-1, Secure Hash Algorithm (SHA-1), 160, 160 0x800C: SHA-256, Secure Hash Algorithm 256 (SHA-256), 256, 256 0x800D: SHA-384, Secure Hash Algorithm 384 (SHA-384), 384, 384 0x800E: SHA-512, Secure Hash Algorithm 512 (SHA-512), 512, 512 0x660E: AES 128, Advanced Encryption Standard 128-bit, 128, 128 0x660F: AES 192, Advanced Encryption Standard 192-bit, 192, 192 0x6610: AES 256, Advanced Encryption Standard 256-bit, 256, 256

Is there any setting or code need to implement into our custom CSP using Smart card to achive the AES decryption email for outlook 2010.

Regards,
