Expand description

SHA-512 output.

The generator state * ctx - is updated to finalize the hash for the previously processed message chunks. The hash is put into * r - .

  • ctx - Generator state.
  • r - Generated hash value.

@remark Initialization of the generator state * ctx - through * ocrypto_sha512_init - is required before this function can be called.

@remark After return, the generator state * ctx - must no longer be used with * ocrypto_sha512_update - and * ocrypto_sha512_final - unless it is reinitialized using * ocrypto_sha512_init - .
