qcrypto_kdf_args

KDF arguments

Synopsis:

#include <qcrypto/qcrypto.h>

typedef struct _qcrypto_kdf_args {
    const uint8_t         *secret;
    size_t                 secretsize;
    const uint8_t         *salt;
    size_t                 saltsize;

        struct {
            size_t   iter;
        } pbkdf2;
        struct {
            const uint8_t *info;
            size_t         infosize;
        } hkdf;
        void        *private;
    };
} qcrypto_kdf_args_t;

Data:

uint8_t* secret: The secret value.
size_t secretsize: The size of the secret value, in bytes.
uint8_t* salt: The salt value.
size_t saltsize: The salt size in bytes.
size_t iter: The number of hash iterations.
uint8_t* info: Extra information.
size_t infosize: The size of the extra information, in bytes
void* private: Private arguments to pass for other KDFs.

Library:

libqcrypto

Description:

Some KDF functions require some additional input to be used in the algorithm.

The private field can be used for custom plugins that implement custom algorithms that the QNX cryptography library API does not support.
