Tools to Generate Short, Secure, URL-friendly, and Unique String Identifiers
Nano IDs are comparable to UUID v4 (random-based). They have a similar number of random bits in the ID (126 in Nano ID and 122 in UUID), so they have similar collision probabilities. Nano ID also use a bigger alphabet, so a similar number of random bits are packed in just 21 symbols instead of 36. The C++ code implements the algorithm specified by Andrey Sitnik.
The following functions are implemented:
nanoid_dict: Built in NanoID alternate character alphabet subsetsNANOIDgenerate: Generate a NanoID
remotes::install_github("hrbrmstr/nanoid")NOTE: To use the ‘remotes’ install options you will need to have the {remotes} package installed.
