This function calculates the SHA-1 checksum of a buffer.
The function allocates the context, performs the calculation, and frees the context.
The SHA-1 result is calculated as output = SHA-1(input buffer).
- Parameters
-
input | The buffer holding the input data. |
ilen | The length of the input data. |
output | The SHA-1 checksum result. |
- Returns
0
if successful
