Detailed Description

RTE Definitions for Asymmetric Cryptography

Defines asymmetric algorithms and modes, as well as supported asymmetric crypto operations.

Definition in file rte_crypto_asym.h.

Macro Definition Documentation

#define RTE_CRYPTO_ASYM_FLAG_PUB_KEY_NO_PADDING RTE_BIT32(0)

Flag to denote public key will be returned without leading zero bytes and if the flag is not set, public key will be padded to the left with zeros to the size of the underlying algorithm (default)

Definition at line 40 of file rte_crypto_asym.h.

#define RTE_CRYPTO_ASYM_FLAG_SHARED_KEY_NO_PADDING RTE_BIT32(1)

Flag to denote shared secret will be returned without leading zero bytes and if the flag is not set, shared secret will be padded to the left with zeros to the size of the underlying algorithm (default)

Definition at line 46 of file rte_crypto_asym.h.

Typedef Documentation

typedef struct rte_crypto_param_t rte_crypto_param

Buffer to hold crypto params required for asym operations.

These buffers can be used for both input to PMD and output from PMD. When used for output from PMD, application has to ensure the buffer is large enough to hold the target data.

If an operation requires the PMD to generate a random number, and the device supports CSRNG, 'data' should be set to NULL. The crypto parameter in question will not be used by the PMD, as it is internally generated.

typedef rte_crypto_param rte_crypto_uint

Unsigned big-integer in big-endian format

Definition at line 211 of file rte_crypto_asym.h.

Enumeration Type Documentation

enum rte_crypto_curve_id

List of elliptic curves. This enum aligns with TLS 'Supported Groups' registry (previously known as NamedCurve registry). FFDH groups are not, and will not be included in this list. Deprecation for selected curve in TLS does not deprecate the selected curve in Cryptodev. https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml

Definition at line 62 of file rte_crypto_asym.h.

enum rte_crypto_asym_xform_type

Asymmetric crypto transformation types. Each xform type maps to one asymmetric algorithm performing specific operation

Enumerator

Invalid xform.
Xform type None. May be supported by PMD to support passthrough op for debugging purpose. if xform_type none , op_type is disregarded.
