Struct lock_keeper::crypto::Decryptor

pub struct Decryptor {
    ciphertext: Vec<u8>,
    context: CryptorContext,
    nonce: Nonce,
    config: SensitiveInfoConfig,
}

The Decryptor type represents a ciphertext encrypted under the ChaCha20Poly1305 scheme for authenticated encryption with associated data (AEAD).

As implied by the scheme name, this uses the recommended 20 rounds and a standard 96-bit nonce. For more details, see the ChaCha20Poly1305 crate.

Fields

ciphertext: Vec<u8>

context: CryptorContext

nonce: Nonce

config: SensitiveInfoConfig

Implementations

impl Decryptor

fn new( ciphertext: Vec<u8>, context: CryptorContext, nonce: Nonce, config: SensitiveInfoConfig ) -> Self

Constructs a new instance of the Decryptor type.

Arguments

• ciphertext - A vector of bytes representing the ciphertext. This is typically the result of the encrypt operation.

• context - An instance of CryptorContext

• nonce - A chacha20poly1305::Nonce instance. This is used in the encryption process to ensure the security of the ciphertext. Every time data is encrypted, a unique nonce should be generated.

Returns

Returns a new instance of the Decryptor type, initialized with the provided ciphertext, context, nonce, and config.

pub fn decrypt( self, decryption_key: &CryptorKey ) -> Result<Encryptor, CryptoError>

Decrypts data using the provided key.

Arguments

• decryption_key - The key used to decrypt the data.

Returns

• A newly created Encryptor instance containing the decrypted data.
• Returns an error of type [CryptoError] if the decryption process fails.

Trait Implementations

impl Clone for Decryptor

fn clone(&self) -> Decryptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Decryptor

An implementation of the std::fmt::Debug trait for Decryptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Decryptor

An implementation of the std::fmt::Display trait for Decryptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Decryptor

Implement the PartialEq trait for the Decryptor type.

fn eq(&self, other: &Self) -> bool

Determines if two Decryptor instances are equal.

This function compares the fields of two Decryptor instances, excluding the config field because the config field does not affect the functional equivalence of two Decryptor instances.

Arguments

• other - The other Decryptor instance to compare with.

Returns

Returns true if the non-config fields are equal between the two Decryptor instances, Otherwise returns false.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
