mbx_x25519¶
Computes a shared secret.
Syntax¶
mbx_status mbx_x25519_mb8(int8u* const pa_shared_key[8], const int8u* const pa_private_key[8], const int8u* const pa_public_key[8]);
Include Files¶
crypto_mb/x25519.h
Parameters¶
pa_shared_key |
Array of pointers to the vectors of computed shared secret values. |
pa_private_key |
Array of pointers to the vectors of own private keys. |
pa_public_key |
Array of pointers to the vectors of party’s public key x-coordinates. |
Description¶
This function computes a shared secret using own private keys specified by pa_private_key and party’s public keys specified by pa_public_key parameters. Each vector must be at least 32-byte length to store the computed shared secret value.
Return Values¶
The mbx_ x25519 function returns the status that indicates whether the operation completed successfully or not. The status value of 0 indicates that all operations completed successfully. The error condition can be analyzed by the MBX_GET_STS() call.
