)Expand description
Expand pseudorandom key to desired length.
@param okm Pointer to len bytes of memory where output keying material is written to.
@param prk Pointer to at least HashLen bytes of memory where pseudorandom key is read from. Usually, this points to the output from the extract step.
@param prklen Length of pseudorandom key.
@param info Pointer to infolen bytes of memory where context and application specific information is read from. Can be a zero-length string.
@param infolen Length of context and application specific information.
@param len Length of output keying material.
