            How to Handle 26-Byte Secret for Time-based One Time Password?
            Asked 2022-Apr-02 at 04:15

            Secret of Time-based One Time Password are usually 16-byte base32 encoded string. e.g. GitHub 2FA.

            But for some scenario, it has 26 bytes long. e.g. Tutanota OTP. Often in lower case with whitespaces, like: vev2 qjea un45 3sr4 q4h3 ais4 ci

            I tried with the TOTP algorithm implemented in dgryski/dgoogauth and tilaklodha/google-authenticator. Both can handle 16-byte secret well, but got error for 26-byte secret.

            A base32 encodes every 5 bits of input bytes into base32 character, go base32 use The RFC 4648 Base 32 alphabet (A-Z, 2-7). When decode a string to bytes, each base32 character input will be mapped to a 5 bit index then recompose to bytes.

            In your example "VEV2QJEAUN453SR4Q4H3AIS4CI", the previous "VEV2QJEAUN453SR4" was already valid input, it is a 16 char input, and 5 bit * 16 is 80 bit so it can be resolved into 10 bytes output. Now let us just look at the rest "Q4H3AIS4CI", 10 char -> 5 * 10 = 50 bits, the previous 40 bits can be decode to 5 bytes, but the last 2 char "CI" leads 2 bit remainder

            As per body-parser's npm page,

            You'll need one of those modules, and you'll then need to read its documentation to see if it provides eg. the req.files you've seen somewhere. Otherwise it will indeed be undefined.

            Both base32 and base64 CLI utils are part of gnu coreutils. So, why not add a base16?

            Answered 2021-Dec-20 at 08:39

            GNU coreutils is free. It's people very, very hard work they are doing for free. You are using it completely for free. How much have you donated? Donate them. Pay them if you want something.

            Why not add a base16 into coreutils?

            It costs work, both implementing, but mostly the never ending maintenance. If something is not needed, it's better not to add it and reduce the work and concentrate on what's important. Maintaining current commands, so they are up-to-date with all systems and be consistent and work, is way more important. Some even say, that (especially in open-source) a project leader has most importantly decide what features to reject, not which to add.

            So, how much will you pay for implementing and then endless maintaining a base16 utility in GNU coreutils?

            The results of both codes differ because of two issues:

            • In the Go Code, the private key is derived incorrectly:

              In the Python code, the path m/44'/118'/0'/0/0' is used, as the output of hdwallet.path() shows. In the Go code, in contrast, the path m/44'/118'/0'/0/0 is used, as shown by the output of path.String().

              To use the path of the Python code in the Go code, the path can be e.g. specified directly. For this the line:

            Memory and time expensive operations. The answer is based on pivotal comment (by Wups):

            If you encode bytes with base64, the result is longer than the input. If you take this result and encode it again in a loop, you have exponential growth.

            • deleting my node_modules folder, reinstalling everything, and rebuilding the app.
            • using path.join(__dirname, '../../', 'node_modules', '.bin', 'electron') as my app.path.

            Jest won't use the babel plugins out of the box, you need to install some additional packages.

            With yarn:

            yarn add --dev babel-jest babel-core regenerator-runtime

            With npm:

            npm install babel-jest babel-core regenerator-runtime --save-dev

            Jest should then pick up the configuration from your .babelrc or babel.config.js.

            Answered 2021-Aug-26 at 15:44

            printf can't be used without a format string : when you call it with a single argument, that argument is parsed as the format.

            Consider its synopsys in man bash :

            printf [-v var] format [arguments]

            It's the arguments list that is optional, not the format.

            man bash goes on saying that plain characters found in the format string are copied as-is to the output stream, which is why you can use printf 'message' as you would echo 'message'.

            However, it also adds that it will identify character escape sequences to convert them before printing (which is similar to what echo -e would do) and most importantly, "format character sequences" (%X substrings) which it will replace by the (possibly transformed) additional parameters, or a default value if there is no parameter left to consume.

            This is the reason why you shouldn't printf "$message" : your $message might contain sequences of characters that will be interpreted by printf.

            If you want to print a message as-is, you will want to use printf '%s' "$message", where %s is the format specifier that asks printf to ouput the (text) parameter as text (so, to output it unmodified).

            In python, the expression \ooo is an octal literal (see "String and byte literals"), so the expression \327 produces the value 215 (hex D7).

            On the other hand, in the shell echo "\327" produces the literal value \327.

            Since you're not encoding the same data in your two examples, you're getting different results.
