+ PKCS#7 is a general-purpose cryptographic standard (defined by RFC2315,

+ Processes a buffer containing binary DER-encoded PKCS7 signature.
+ The signed data content may be embedded within the buffer or separated. Funtion
+ verifies the signature of the content is valid and signing certificate was not
+ revoked and is contained within a list of trusted signers.
+
+ @param[in] This Pointer to EFI_PKCS7_VERIFY_PROTOCOL instance.
+ @param[in] SignedData Points to buffer containing ASN.1 DER-encoded PKCS7
+ signature.
+ @param[in] SignedDataSize The size of SignedData buffer in bytes.
+ @param[in] InData In case of detached signature, InData points to
+ buffer containing the raw message data previously
+ signed and to be verified by function. In case of
+ SignedData containing embedded data, InData must be
+ NULL.
+ @param[in] InDataSize When InData is used, the size of InData buffer in
+ bytes. When InData is NULL. This parameter must be
+ 0.
+ @param[in] AllowedDb Pointer to a list of pointers to EFI_SIGNATURE_LIST
+ structures. The list is terminated by a null
+ pointer. The EFI_SIGNATURE_LIST structures contain
+ lists of X.509 certificates of approved signers.
+ Function recognizes signer certificates of type
+ EFI_CERT_X509_GUID. Any hash certificate in AllowedDb
+ list is ignored by this function. Function returns
+ success if signer of the buffer is within this list
+ (and not within RevokedDb). This parameter is
+ required.
+ @param[in] RevokedDb Optional pointer to a list of pointers to
+ EFI_SIGNATURE_LIST structures. The list is terminated
+ by a null pointer. List of X.509 certificates of
+ revoked signers and revoked file hashes. Except as
+ noted in description of TimeStampDb signature
+ verification will always fail if the signer of the
+ file or the hash of the data component of the buffer
+ is in RevokedDb list. This list is optional and
+ caller may pass Null or pointer to NULL if not
+ required.
+ @param[in] TimeStampDb Optional pointer to a list of pointers to
+ EFI_SIGNATURE_LIST structures. The list is terminated
+ by a null pointer. This parameter can be used to pass
+ a list of X.509 certificates of trusted time stamp
+ signers. This list is optional and caller must pass
+ Null or pointer to NULL if not required.
+ @param[out] Content On input, points to an optional caller-allocated
+ buffer into which the function will copy the content
+ portion of the file after verification succeeds.
+ This parameter is optional and if NULL, no copy of
+ content from file is performed.
+ @param[in,out] ContentSize On input, points to the size in bytes of the optional
+ buffer Content previously allocated by caller. On
+ output, if the verification succeeds, the value
+ referenced by ContentSize will contain the actual
+ size of the content from signed file. If ContentSize
+ indicates the caller-allocated buffer is too small
+ to contain content, an error is returned, and
+ ContentSize will be updated with the required size.
+ This parameter must be 0 if Content is Null.
+
+ @retval EFI_SUCCESS Content signature was verified against hash of
+ content, the signer's certificate was not found in
+ RevokedDb, and was found in AllowedDb or if in signer
+ is found in both AllowedDb and RevokedDb, the
+ signing was allowed by reference to TimeStampDb as
+ described above, and no hash matching content hash
+ was found in RevokedDb.
+ @retval EFI_SECURITY_VIOLATION The SignedData buffer was correctly formatted but
+ signer was in RevokedDb or not in AllowedDb. Also
+ returned if matching content hash found in RevokedDb.
+ @retval EFI_COMPROMISED_DATA Calculated hash differs from signed hash.
+ @retval EFI_INVALID_PARAMETER SignedData is NULL or SignedDataSize is zero.
+ AllowedDb is NULL.
+ @retval EFI_INVALID_PARAMETER Content is not NULL and ContentSize is NULL.
+ @retval EFI_ABORTED Unsupported or invalid format in TimeStampDb,
+ RevokedDb or AllowedDb list contents was detected.
+ @retval EFI_NOT_FOUND Content not found because InData is NULL and no
+ content embedded in SignedData.
+ @retval EFI_UNSUPPORTED The SignedData buffer was not correctly formatted
+ for processing by the function.
+ @retval EFI_UNSUPPORTED Signed data embedded in SignedData but InData is not
+ NULL.
+ @retval EFI_BUFFER_TOO_SMALL The size of buffer indicated by ContentSize is too
+ small to hold the content. ContentSize updated to
+ required size.
