mbx_ed25519_verify_mb8
Verifies signature.
Syntax
mbx_status mbx_ed25519_verify_mb8(const ed25519_sign_component* const pa_sign_r[8], const ed25519_sign_component* const pa_sign_s[8], const int8u* const pa_msg[8], const int32u msgLen[8], const ed25519_public_key* const pa_public_key[8]);

Parameters
pa_sign_r |
Array of pointers to the signature’s r- components of 32 bytes length each. |
pa_sign_s |
Array of pointers to the signature’s s- components of 32 bytes length each. |
pa_msg |
Array of pointers to the messages. |
msgLen |
Array of the message’s lengths above in bytes. |
pa_public_key |
Array of pointers to the public keys of 32 bytes length each. |
Description
The mbx_ed25519_verify_mb8 function verifies signatures specified by pa_sign_r[i] and pa_sign_s[i] parameters. Other parameters pa_msg[], msgLen[], and pa_public_key[] specify other input parameters for verification.
Return Values
The mbx_ ed25519_public_key_mb8 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. The result of verification is returned as status too. The MBX_STATUS_OK value means that signature is verified, else status contains MBX_STATUS_SIGNATURE_ERR value.
