typedef BOOLEAN(EFIAPI * EDKII_CRYPTO_AES_CBC_DECRYPT) (IN VOID *AesContext, IN CONST UINT8 *Input, IN UINTN InputSize, IN CONST UINT8 *Ivec, OUT UINT8 *Output)

Performs AES decryption on a data buffer of the specified size in CBC mode.

This function performs AES decryption on data buffer pointed by Input, of specified size of InputSize, in CBC mode. InputSize must be multiple of block size (16 bytes). This function does not perform padding. Caller must perform padding, if necessary, to ensure valid input data size. Initialization vector should be one block size (16 bytes).

If AesContext is NULL, then return FALSE. If Input is NULL, then return FALSE. If InputSize is not multiple of block size (16 bytes), then return FALSE. If Ivec is NULL, then return FALSE. If Output is NULL, then return FALSE. If this interface is not supported, then return FALSE.

Parameters

[in]	Input	Pointer to the buffer containing the data to be encrypted.
[in]	InputSize	Size of the Input buffer in bytes.
[in]	Ivec	Pointer to initialization vector.
[out]	Output	Pointer to a buffer that receives the AES encryption output.

Return values

TRUE	AES decryption succeeded.

VerifyEKUsInPkcs7Signature()

This function receives a PKCS7 formatted signature, and then verifies that the specified Enhanced or Extended Key Usages (EKU's) are present in the end-entity leaf signing certificate.

Note that this function does not validate the certificate chain.

Applications for custom EKU's are quite flexible. For example, a policy EKU may be present in an Issuing Certificate Authority (CA), and any sub-ordinate certificate issued might also contain this EKU, thus constraining the sub-ordinate certificate. Other applications might allow a certificate embedded in a device to specify that other Object Identifiers (OIDs) are present which contains binary data specifying custom capabilities that the device is able to do.

Parameters

[in]	Pkcs7Signature	- The PKCS#7 signed information content block. An array containing the content block with both the signature, the signer's certificate, and any necessary intermediate certificates.
[in]	Pkcs7SignatureSize	- Number of bytes in Pkcs7Signature.
[in]	RequiredEKUs	- Array of null-terminated strings listing OIDs of required EKUs that must be present in the signature.
[in]	RequiredEKUsSize	- Number of elements in the RequiredEKUs string array.
[in]	RequireAllPresent	- If this is TRUE, then all of the specified EKU's must be present in the leaf signer. If it is FALSE, then we will succeed if we find any of the specified EKU's.

Return values

EFI_SUCCESS	- The required EKUs were found in the signature.
EFI_INVALID_PARAMETER	- A parameter was invalid.
EFI_NOT_FOUND	- One or more EKU's were not found in the signature.
