Fapi_Unseal (FAPI_CONTEXT * context, char const * path, uint8_t ** data, size_t * size)¶
One-Call function for Fapi_Unseal
Unseals data from a seal in the FAPI metadata store.
Parameters:
context The FAPI_CONTEXT
path The path to the sealed data
data The decrypted data after unsealing. May be NULL
size The size of data in bytes. May be NULL
path The path to the sealed data
data The decrypted data after unsealing. May be NULL
size The size of data in bytes. May be NULL

TSS2_RC_SUCCESS if the function call was a
success.
