Struct Aes256Gcm

pub struct Aes256Gcm { /* private fields */ }

AES-256-GCM encryption implementation

Implementations

impl Aes256Gcm

pub async fn from_key(data: &[u8]) -> Result<Self, ImportKeyError>

Creates a new AES-256-GCM instance from a raw key.

Arguments

• data - Raw key bytes (should be 32 bytes for AES-256)

Returns

Result containing the Aes256Gcm instance or an ImportKeyError

Errors

• ImportKeyError::Syntax if key usage array is empty
• ImportKeyError::Type if key format/data is invalid
• ImportKeyError::InvalidKeyFormat if provided key format is invalid
