Struct ExportedKey 

pub struct ExportedKey {
    pub format_version: u32,
    pub exported_at: SystemTime,
    pub wrapping_algorithm: Algorithm,
    pub salt: Vec<u8>,
    pub argon2_params: ExportArgon2Params,
    pub encrypted_key: Vec<u8>,
    pub metadata: KeyMetadata,
    pub comment: Option<String>,
}

A cryptographic key exported in a secure, portable format

The key material is encrypted using a password-derived key (Argon2id). The format is versioned to support future compatibility.

Fields

format_version: u32

Format version for compatibility

exported_at: SystemTime

When the key was exported

wrapping_algorithm: Algorithm

Algorithm used to wrap/encrypt the key

salt: Vec<u8>

Salt used for password derivation (32 bytes)

argon2_params: ExportArgon2Params

Argon2 parameters used for derivation

encrypted_key: Vec<u8>

Encrypted key material (nonce + ciphertext + tag)

metadata: KeyMetadata

Key metadata (stored in plaintext for validation)

comment: Option<String>

Optional comment/description

Implementations

impl ExportedKey

pub fn new( key: &SecretKey, metadata: KeyMetadata, password: &[u8], wrapping_algorithm: Algorithm, ) -> Result<Self>

pub fn decrypt(&self, password: &[u8]) -> Result<SecretKey>

Decrypt and extract the key material

pub fn with_comment<S: Into<String>>(self, comment: S) -> Self

Deserialize from JSON

pub fn to_bytes(&self) -> Result<Vec<u8>>

Serialize to bytes (using bincode or similar)
