psa_verify_hash_complete() function

#PSA_SUCCESS Operation completed successfully, and the passed signature is valid. #PSA_OPERATION_INCOMPLETE Operation was interrupted due to the setting of \c psa_interruptible_set_max_ops(). There is still work to be done. Call this function again with the same operation object. #PSA_ERROR_INVALID_HANDLE \emptydescription #PSA_ERROR_INVALID_SIGNATURE The calculation was performed successfully, but the passed signature is not a valid signature. #PSA_ERROR_BAD_STATE An operation was not previously started on this context via \c psa_verify_hash_start(). #PSA_ERROR_NOT_SUPPORTED \emptydescription #PSA_ERROR_INVALID_ARGUMENT \emptydescription #PSA_ERROR_INSUFFICIENT_MEMORY \emptydescription #PSA_ERROR_COMMUNICATION_FAILURE \emptydescription #PSA_ERROR_HARDWARE_FAILURE \emptydescription #PSA_ERROR_CORRUPTION_DETECTED \emptydescription #PSA_ERROR_STORAGE_FAILURE \emptydescription #PSA_ERROR_DATA_CORRUPT \emptydescription #PSA_ERROR_DATA_INVALID \emptydescription #PSA_ERROR_INSUFFICIENT_ENTROPY \emptydescription #PSA_ERROR_BAD_STATE The library has either not been previously initialized by psa_crypto_init() or you did not previously call psa_verify_hash_start() on this object. It is implementation-dependent whether a failure to initialize results in this error code.

This function combined with \c psa_verify_hash_start() is equivalent to \c psa_verify_hash() but this function can return early and resume according to the limit set with \c psa_interruptible_set_max_ops() to reduce the maximum time spent in a function call. Users should call this function on the same operation object repeatedly until it either returns 0 or an error. This function will return #PSA_OPERATION_INCOMPLETE if there is more work to do. Alternatively users can call \c psa_verify_hash_abort() at any point if they no longer want the result. When this function returns successfully, the operation becomes inactive. If this function returns an error status, the operation enters an error state and must be aborted by calling \c psa_verify_hash_abort().
