Module safe_app::utils

Utility functions.

Modules

logging	Logging utilities. These functions can initialise logging for output to stdout only, or to a file and stdout. For more fine-grained control, create a file called log.toml in the root directory of the project, or in the same directory where the executable is. See log4rs docs for details about the format and structure of this file.
test_utils	Common utility functions for writing test cases.

Constants

SYM_ENC_KEY_LEN	Length of the symmetric encryption key.
SYM_ENC_NONCE_LEN	Length of the nonce used for symmetric encryption.

Traits

FutureExt

Additional future combinators.

Functions

bin_data_format	Convert binary data to a diplay-able format
derive_secrets	Derive Password, Keyword and PIN (in order).
generate_nonce	Generates a nonce for symmetric encryption
generate_random_string	Generates a String from length random UTF-8 chars. Note that the NULL character will be excluded to allow conversion to a CString if required, and that the actual len() of the returned String will likely be around 4 * length as most of the randomly-generated chars will consume 4 elements of the String.
generate_random_string_rng	Generates a random String using provided length and rng.
generate_random_vector	Generate a random vector of given length.
generate_random_vector_rng	Generates a random vector using provided length and rng.
generate_readable_string	Generates a readable String using only ASCII characters.
generate_readable_string_rng	Generates a readable String using provided length and `rng.
generate_sym_enc_key	Generates a symmetric encryption key
symmetric_decrypt	Symmetric decryption.
symmetric_encrypt	Symmetric encryption. If nonce is None, then it will be generated randomly.

Type Definitions

SymEncKey	Symmetric encryption key
SymEncNonce	Symmetric encryption nonce
