- 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

- for processing by the function.
- @retval EFI_UNSUPPORTED Signed data embedded in SignedData but InData is not
- NULL.

- Processes a buffer containing binary DER-encoded detached PKCS7 signature.

- 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] Signature Points to buffer containing ASN.1 DER-encoded PKCS
- detached signature.
- @param[in] SignatureSize The size of Signature buffer in bytes.
- @param[in] InHash InHash points to buffer containing the caller
- calculated hash of the data. The parameter may not
- be NULL.
- @param[in] InHashSize The size in bytes of InHash buffer.
- @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. 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 parameter is optional
- and caller may pass 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
- counter-signers.
