psa_sign_hash_abort() function
Abort a sign hash operation. \warning This is a beta API, and thus subject to change at any point. It is not bound by the usual interface stability promises.
Syntax
Implemented in ![]()
psa_crypto.c:3630
Return value
#PSA_SUCCESS The operation was aborted successfully. #PSA_ERROR_NOT_SUPPORTED \emptydescription #PSA_ERROR_BAD_STATE The library has not been previously initialized by psa_crypto_init(). It is implementation-dependent whether a failure to initialize results in this error code.
Notes
This function is the only function that clears the number of ops completed as part of the operation. Please ensure you copy this value via \c psa_sign_hash_get_num_ops() if required before calling. Aborting an operation frees all associated resources except for the \p operation structure itself. Once aborted, the operation object can be reused for another operation by calling \c psa_sign_hash_start() again. You may call this function any time after the operation object has been initialized. In particular, calling \c psa_sign_hash_abort() after the operation has already been terminated by a call to \c psa_sign_hash_abort() or psa_sign_hash_complete() is safe.

Description
Get the number of ops that a hash signing operation has taken so far. If the operation has completed, then this will represent the number of ops required for the entire operation. After initialization or calling \c psa_sign_hash_interruptible_abort() on the operation, a value of 0 will be returned. \warning This is a beta API, and thus subject to change at any point. It is not bound by the usual interface stability promises. This is a helper provided to help you tune the value passed to \c psa_interruptible_set_max_ops().
Start signing a hash or short message with a private key, in an interruptible manner. \see \c psa_sign_hash_complete() \warning This is a beta API, and thus subject to change at any point. It is not bound by the usual interface stability promises.
Continue and eventually complete the action of signing a hash or short message with a private key, in an interruptible manner. \see \c psa_sign_hash_start() \warning This is a beta API, and thus subject to change at any point. It is not bound by the usual interface stability promises.
