Crate fnzero_safe 

FnzSafe

A Solana key management library with authenticated password keystores.

Features

• Simple Encryption: Password-based encryption for Solana private keys
• Triple-Factor Authentication: Hardware fingerprint + master password + security question
• 2FA Support: TOTP-based two-factor authentication
• Cross-Platform: Works on macOS, Linux, and Windows

Quick Start

use fnzero_safe::{KeyManager, EncryptionResult};

// Generate a new Solana keypair
let keypair = KeyManager::generate_keypair();

// Encrypt with password
let encrypted = KeyManager::encrypt_with_password(
    &keypair.to_base58_string(),
    "my_strong_password"
).unwrap();

// Decrypt with password
let decrypted = KeyManager::decrypt_with_password(
    &encrypted,
    "my_strong_password"
).unwrap();

Constants

KEYSTORE_V2_VERSION

KEYSTORE_V3_VERSION

MAX_KEYSTORE_JSON_BYTES

MAX_PASSWORD_LENGTH

Maximum password size accepted by v2 operations, measured in UTF-8 bytes.

MIN_PASSWORD_LENGTH

Minimum password length for encryption/decryption

Traits

Signer

The Signer trait declares operations that all digital signature providers must support. It is the primary interface by which signers are specified in Transaction signing interfaces

Functions

decrypt_key

Decrypt a base64-encoded legacy encrypted string with a 32-byte key.

decrypt_key_to_bytes

Decrypt to raw bytes (used when plaintext may be base58 string or 64-byte keypair).

encrypt_key

Encrypt a string with the legacy unauthenticated format.

generate_encryption_key_simple

Derive the legacy v1 key. New password keystores use Argon2id instead.

Type Aliases

EncryptionResult

Result type for encryption operations
