Basic codes are simple, predefined formats used for generating random strings tailored to specific readability, security, or usability requirements. This section presents several common types of such codes, each optimized for different use cases-from visually clear uppercase sequences to complex, high-entropy passwords and pronounceable patterns suitable for verbal communication.
In the case of strings of characters containing upper and lower case letters, reading them is often difficult, for this reason, if the code is to be read by a human, let alone rewritten, it is recommended to use a uniform character size, e.g. using only upper case letters. Below is an example of several such 6 character codes.
One of the most basic examples of generated codes may be a random string of characters consisting of letters and numbers.
Sometimes it may be necessary to generate strings of characters consisting of all printable ASCII characters (letters, numbers and special characters). The following example shows in simple way how multiple patterns can be used at once.
In many cases where codes are to be distributed in a way that requires reading or rewriting, it is good practice to not use similar characters, such as 0 (zero) or O (capital letter o).
Strong passwords should, above all, be long. OWASP ASVS 4.0 recommends that they be at least 12 characters long, which will make breaking them relatively unprofitable. It's a good idea not to rely on minimum requirements, which is why we recommend using at least 16-character, random passwords using letters, numbers and special characters.
If codes are to be transcribed or dictated, it is a good idea to structure them in a way that is easy to read and pronounce. For this purpose, a construction with alternating vowels and consonants can be used.
