    Hi,

      I am having problems trying to retrieve the timestamp encoded in a
    pkcs#7 digital signature.

      I am using MS CryptoAPI and I extract the authenticated attribute
    using the CryptMsgGetParam(...) function. After all processing is done,
    I get a pointer to a CRYPT_ATTR_BLOB structure, which in turn provides
    me with a BYTE* (with the timestamp info).

      The problem is how to process this BYTE* to extract the original
    timestamp information... how is it encoded ? Does anyone know where can
    I find this information ?

      Thank you,
      Sérgio
