* @brief Calculate a SHA1 checksum of data

|
*
|
|
* This function calculates a SHA1 checksum of the binary data pointed to by
|
|
* @p data of size @p size in bytes and will fill 20 bytes pointed to by
|
|
* @p dst with the resulting 20 byte binary SHA1 sum.
|
|
*
|
|
* The input data should be a valid pointer to at least @p size bytes of data
|
|
* that will be summed. @p dst should also point to a buffer of at least 20
|
|
* bytes in size to store the checksum.
