Excuse me, I speak Spanish. I am self-taught in computer science and I ventured to make a payment system for my small shop. the problem is; that for my billing system to work the algorithms are missing: presumed rc4, verhoeff and base64, in VBA language, I don't understand this and I wanted to ask if you had any of this among your algorithms that you could share with me, I am very grateful.
The algorithms must satisfy the result of the following examples:
'*******input data
Authorization: maximum fifteen digits (numbers).
Invoice: maximum twelve digits (numbers).
DNI: minimum value = zero (one digit), maximum twelve digits (numbers).
Date: YYYYMMDD, eight digits (numbers).
Cost: minimum value = 1, no maximum value (rounded number).
Password: up to 256 characters.
A, B, C, D, E, F, G, H, I, J, K, L, M, N, P, Q, R, S, T, U, V, W, X, Y, Z,
a, b, c, d, e, f, g, h, i, j, k, m, n, p, q, r, s, t, u, v, w, x, y, z, 2,
3, 4, 5, 6, 7, 8, 9, =, #, (, ), *, +, -, _, \, @, [, ], {, }, %, $
'*******process:
Algorithms: verhoeff, base64, alleged RC4
'*******result:
Control code: generated from the aforementioned algorithms, it will be an alphanumeric data of up to ten characters, represented in groups of 2 separated by the character "-". Example: 7B-CD-23-04-12
Example:
