NAME¶
kcapi_aead_getdata - get the resulting data from encryption
SYNOPSIS¶
void kcapi_aead_getdata(struct kcapi_handle * handle, uint8_t * encdata, uint32_t encdatalen, uint8_t ** aad, uint32_t * aadlen, uint8_t ** data, uint32_t * datalen, uint8_t ** tag, uint32_t * taglen);
ARGUMENTS¶
handle
[in] cipher handle
encdata
[in] data buffer returned by the encryption
operation
encdatalen
[in] size of the encryption data buffer
aad
[out] AD buffer pointer; when set to NULL, no data
pointer is returned
aadlen
[out] length of AD; when aad was set to NULL, no
information is returned
data
[out] pointer to output buffer from AEAD encryption
operation when set to NULL, no data pointer is returned
datalen
[out] length of data buffer; when data was set to NULL,
no information is returned
tag
[out] tag buffer pointer; when set to NULL, no data
pointer is returned
taglen
[out] length of tag; when tag was set to NULL, no
information is returned
DESCRIPTION¶
DEPRECATED since 0.13.0
This function is a service function to the consumer to locate the right ciphertext buffer offset holding the authentication tag. In addition, it provides the consumer with the length of the tag and the length of the ciphertext.
