Provides functionality related to Edwards-curve Digital Signature Algorithm (EdDSA).
#define NRF_CRYPTO_EDDSA_ED25519_SIGNATURE_SIZE (2 * 256 / 8) |
Size of the EdDSA Ed25519 signature.
<Context used to store temporary data during the signing with EdDSA Ed25519.
Sign a message using Edwards-curve Digital Signature Algorithm (EdDSA).
- Parameters
-
[in] | p_context | Pointer to the temporary structure that holds context information. If it is NULL, the required data is allocated with NRF_CRYPTO_ALLOC and freed at the end of the function. |
[in] | p_private_key | Pointer to the structure that holds a private key. |
[in] | p_message | Pointer to the message to sign. |
[in] | message_size | Number of bytes in p_message. |
[out] | p_signature | Pointer to the array where EdDSA signature is to be put. Minimum bytes required: NRF_CRYPTO_EDDSA_ED25519_SIGNATURE_SIZE. |
[in,out] | p_signature_size | Pointer to the maximum number of bytes that p_signature buffer can hold on input, and to the actual number of bytes used by the data on output (NRF_CRYPTO_EDDSA_ED25519_SIGNATURE_SIZE). |
- Returns
- NRF_SUCCESS on success.

- Parameters
-
[in] | p_context | Pointer to the temporary structure that holds context information. If it is NULL, necessary data is allocated with NRF_CRYPTO_ALLOC and freed at the end of the function. |
[in] | p_public_key | Pointer to the structure that holds a public key. |
[in] | p_message | Pointer to the message to verify. |
[in] | message_size | Number of bytes in p_message. |
[in] | p_signature | Pointer to the array that contains EdDSA signature. |
[in] | signature_size | Number of bytes in p_signature. |
- Returns
- NRF_SUCCESS on success.
