## Field Documentation

### enum rte\_crypto\_asym\_ke\_type ke\_type

Key exchange operation type

Definition at line **474** of file **rte\_crypto\_asym.h**.

### rte\_crypto\_uint priv\_key

Output - generated private key when ke\_type is RTE\_CRYPTO\_ASYM\_KE\_PRIV\_KEY\_GENERATE.

Input - private key when ke\_type is one of: RTE\_CRYPTO\_ASYM\_KE\_PUB\_KEY\_GENERATE, RTE\_CRYPTO\_ASYM\_KE\_SHARED\_SECRET\_COMPUTE.

In case priv\_key.length is 0 and ke\_type is set with RTE\_CRYPTO\_ASYM\_KE\_PUB\_KEY\_GENERATE, CSRNG capable device will generate a private key and use it for public key generation.

### rte\_crypto\_uint pub\_key

Output - generated public key when ke\_type is RTE\_CRYPTO\_ASYM\_KE\_PUB\_KEY\_GENERATE.

Input - peer's public key when ke\_type is RTE\_CRYPTO\_ASYM\_KE\_SHARED\_SECRET\_COMPUTE.

Definition at line **490** of file **rte\_crypto\_asym.h**.

### rte\_crypto\_uint shared\_secret

Output - calculated shared secret when ke\_type is RTE\_CRYPTO\_ASYM\_KE\_SHARED\_SECRET\_COMPUTE.

Definition at line **498** of file **rte\_crypto\_asym.h**.
