The number system in base 36 is called alphanumeric system and uses for its representation the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G , H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z. There are cases in which the letters can be uppercase and lowercase.
It has this name because the symbols used for its representation coincide with the traditional computational definition of a numeric character. It is important to take into account that the alphabetic characters used belong to the Latin alphabet of the English language.
The alphanumeric system , in the area of computing, is not as effective an option as the binary, hexadecimal or any other number system.
On the other hand, the alphanumeric system can serve as an alternative with respect to other minor base systems when identifying the objects of a set, since the same quantity can be represented with a much smaller chain of symbols .
A clear example of this can be the allocation of a number of patents.
To enter various computer systems, it is mandatory to enter a password, mostly this procedure is carried out by people who wish to enter their email or carry out a banking transaction on the internet. In most cases, companies give the user the option of choosing an alphanumeric key (that is, combining numbers with letters).
Using this option, you increase the possible combinations of symbols and decrypting the password is practically impossible, in case the password of your email is “hello” a hacker could decrypt it quickly unlike a password that is “gRi49rs6P”.
When obtaining a password it is important to take into account certain recommendations such as:
- It must include at least 8 digits.
- It is advisable to change the alphanumeric password from time to time, in this way any personal space is protected.
- It is necessary to take into account that the same password cannot be used for all accounts.
- In case you want to set an alphanumeric password with personal details, it is recommended to include special letters and numbers.
