Preprocessor macro definitions for the cryptodev.h header file in the devcr library
#define AALG_MAX_RESULT_LEN 64
Maximum algorithm result length.
#define HASH_MAX_LEN AALG_MAX_RESULT_LEN
Maximum hash algorithm result length.
#define CRYPTO_HMAC_MAX_KEY_LEN 512
Maximum HMAC key length.
#define CRYPTO_CIPHER_MAX_KEY_LEN 64
Maximum cipher key length.
#define CRIOGET_NOT_NEEDED 1
CRIOGET command file descriptor duplicate flag. This flag indicates that to use the cryptography device for operations, a driver doesn't require the caller to call ioctl(fd, CRIOGET, &dupfd) to get an extra file descriptor.
