qcrypto_signature_args_t

Updated: October 26, 2022

Signature arguments

Synopsis:

#include <qcrypto/qcrypto.h>
typedef struct _qcrypto_signature_args {
    qcrypto_signature_mode_t mode;
    union {
        struct {
            qcrypto_rsa_pad_mode_t pad_mode;
            size_t saltsize;
        } rsa;
        void* private;
    };
} qcrypto_signature_args_t;

Data:

qcrypto_signature_mode_t mode

The signature operation type.

qcrypto_rsa_pad_mode_t pad_mode

The padding mode.

size_t saltsize

The PSS salt size.

void* private

Private arguments to pass for other signature algorithms.

Library:

libqcrypto

Description:

Some signature modes require additional arguments as input to configure the algorithm. The private field can be used for custom plugins that implement custom algorithms that the QNX cryptography library API does not support.
