This extrinsic function returns the SHA hash of a message that is too long to be passed as a single string. The message is passed in ^TMP($J,MSUB). The message should be broken into blocks that are exactly 64 bytes/characters long except for the last one. ^TMP($J,MSG,N) is the Nth block of the message; where N runs from 1 to NBLOCKS.
NOTE: This API was released with Kernel patch XU*8.0*657.
|hashlen||(required) The hash length in bits:
|msub||(required) The ^TMP($J,msub) subscript in which the message is passed.|
|nblocks||(required) The number of blocks in the message.|
