set mime [new_CkMime]

# Load the MIME
set success [CkMime_LoadMimeFile $mime "encrypted.mim"]

# Decrypt using a specific PFX file:
set pfxPassword "myPassword"

if {$success == 0} then {

    delete_CkMime $mime
    exit

# Display the decrypted MIME:
puts [CkMime_getMime $mime]

# Note: The MIME to be decrypted should look something like this
# when viewed in a text editor:
# (Note that the Content-Type is application/x-pkcs7-mime)

# Content-Disposition: attachment; filename="smime.p7m"
# Content-Transfer-Encoding: base64
# Content-Type: application/x-pkcs7-mime;
