This source reference follows declared modules and preserves feature attributes. It includes public declarations and implementation methods in those modules. Private-module exports and trait resolution still require the compiler; not every declaration is a crate-root import. Function bodies and constant values are omitted. Source comments describe their implementation context and are not a production deployment claim.

aead::AES256GCM_KEY_LEN

Length of an AES-256-GCM key in bytes.

pub const AES256GCM_KEY_LEN: usize;

Source line: 22.

aead::AES256GCM_NONCE_LEN

Length of an AES-256-GCM nonce in bytes (96 bits, recommended).

pub const AES256GCM_NONCE_LEN: usize;

Source line: 24.

aead::XCHACHA20POLY1305_KEY_LEN

Length of an XChaCha20-Poly1305 key in bytes.

pub const XCHACHA20POLY1305_KEY_LEN: usize;

Source line: 27.

aead::XCHACHA20POLY1305_NONCE_LEN

Length of an XChaCha20-Poly1305 nonce in bytes (192 bits, extended).

pub const XCHACHA20POLY1305_NONCE_LEN: usize;

Source line: 29.

aead::aes256gcm_encrypt

Encrypts plaintext with AES-256-GCM.

Returns ciphertext || tag (16-byte tag appended).

Errors

• [CryptoError::InvalidLength] if key or nonce has the wrong length.
• [CryptoError::AeadFailed] if the underlying cipher rejects the input.

pub fn aes256gcm_encrypt(
    key: &[u8],
    nonce: &[u8],
    plaintext: &[u8],
    aad: &[u8],
) -> Result<Vec<u8>, CryptoError>;

Source line: 39.

aead::aes256gcm_decrypt

Decrypts ciphertext with AES-256-GCM, verifying the tag.

ciphertext must be actual_ciphertext || tag. Returns the plaintext on successful tag verification.

Errors

• [CryptoError::InvalidLength] if key or nonce has the wrong length.
• [CryptoError::AeadFailed] (operation = "decrypt") on tag failure.

pub fn aes256gcm_decrypt(
    key: &[u8],
    nonce: &[u8],
    ciphertext: &[u8],
    aad: &[u8],
) -> Result<Vec<u8>, CryptoError>;

Source line: 89.

aead::xchacha20poly1305_encrypt

Encrypts plaintext with XChaCha20-Poly1305 (extended-nonce variant).

Returns ciphertext || tag (16-byte tag appended).

Errors

• [CryptoError::InvalidLength] if key or nonce has the wrong length.
• [CryptoError::AeadFailed] if the cipher rejects the input.

pub fn xchacha20poly1305_encrypt(
    key: &[u8],
    nonce: &[u8],
    plaintext: &[u8],
    aad: &[u8],
) -> Result<Vec<u8>, CryptoError>;
