Binary package “r-cran-base64url” in ubuntu oracular
GNU R fast and URL-safe Base64 encoder and decoder
In contrast to RFC3548, the 62nd character ("+") is replaced with
"-", the 63rd character ("/") is replaced with "_". Furthermore, the encoder
does not fill the string with trailing "=". The resulting encoded strings
comply to the regular expression pattern "[A-Za-z0-9_-]" and thus are
safe to use in URLs or for file names.
The package also comes with a simple base32 encoder/decoder suited for
case insensitive file systems.
