Struct EncryptedKeyContainer 

pub struct EncryptedKeyContainer {
    pub version: u8,
    pub salt: String,
    pub nonce: String,
    pub ciphertext: String,
    pub public_key: Option<String>,
}

Encrypted key container format (devsyrem’s versioned format)

This structure holds all data needed to decrypt a private key:

• Salt for key derivation
• Nonce for AES-GCM
• Encrypted private key (ciphertext + auth tag)

The container can be serialized to JSON for storage/transmission.

Fields

version: u8

Version for future format changes

salt: String

Salt for Argon2 key derivation (base64)

nonce: String

Nonce for AES-GCM (base64)

ciphertext: String

Encrypted private key with auth tag (base64)

public_key: Option<String>

Public key for verification (base58, optional)

Implementations

impl EncryptedKeyContainer

pub fn encrypt( private_key: &[u8], passphrase: &str, ) -> Result<Self, SignerError>

Create a new encrypted key container from a plaintext private key

Arguments

• private_key - The 32-byte Ed25519 seed or 64-byte keypair
• passphrase - The passphrase to encrypt with

Returns

The encrypted container

Memory Lifecycle

The private key is copied into a secure buffer for processing, and all intermediate values are zeroized.

pub fn to_json(&self) -> Result<String, SignerError>

Serialize the container to JSON

pub fn from_json(json: &str) -> Result<Self, SignerError>

Deserialize from JSON

Trait Implementations

impl Clone for EncryptedKeyContainer

fn clone(&self) -> EncryptedKeyContainer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for EncryptedKeyContainer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Serialize for EncryptedKeyContainer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
