## 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 **41** 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 **47** of file **rte\_crypto\_asym.h**.

### #define RTE\_CRYPTO\_ASYM\_FLAG\_PUB\_KEY\_COMPRESSED RTE\_BIT32(2)

Flag to denote public key will be returned in compressed form

Definition at line **51** 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 **225** 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\_edward\_instance

List of Edwards curve instances as per RFC 8032 (Section 5).
