Check input P7Data is a wrapped ContentInfo structure or not. If not construct
|
||
|

a new structure to wrap P7Data.

|
|
Caution: This function may receive untrusted input.
|

|
UEFI Authenticated Variable is external input, so this function will do basic
|

|
|
check for PKCS#7 data structure.
|

|
|
|
||
|
|
@param[in] P7Data Pointer to the PKCS#7 message to verify.
|

|
@param[in] P7Length Length of the PKCS#7 message in bytes.

@param[out] WrapFlag If TRUE P7Data is a ContentInfo structure, otherwise
|

|

return FALSE.

@param[out] WrapData If return status of this function is TRUE:
|
||
|
|
1) when WrapFlag is TRUE, pointer to P7Data.
|
||
|
|
2) when WrapFlag is FALSE, pointer to a new ContentInfo
|
||
|
|
structure. It's caller's responsibility to free this
|
||
|
|
buffer.
|
||
|
|
@param[out] WrapDataSize Length of ContentInfo structure in bytes.
|
||
|
|
|

@retval TRUE The operation is finished successfully.
|
