| Type: | Package |
| Title: | Fast and URL-Safe Base64 Encoder and Decoder |
| Version: | 1.4 |
| Description: | 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. |

Encode to base32 or Decode from base32
Description
Simple RFC4648 base32 encoder/decoder. Pads with “=”.
Usage
base32_encode(x, use.padding = FALSE)
base32_decode(x, use.padding = FALSE)
Arguments
x |
[ |
use.padding |
[ |
Value
[character] of the same length as input x.
References
Implementation based on base32 encoder/decoder in the GNU lib: https://www.gnu.org/software/gnulib/.
Examples
x = "plain text"
encoded = base32_encode(x)
decoded = base32_decode(encoded)
print(encoded)
print(decoded)
Encode to base64 or Decode from base64
Description
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.
Usage
base64_urlencode(x)
base64_urldecode(x)
Arguments
x |
[ |
Value
[character] of the same length as input x.
References
Implementation based on base64 encoder/decoder in the Apache Portable Runtime (APR): https://svn.apache.org/repos/asf/apr/apr/trunk/encoding/apr_base64.c
Examples
x = "plain text"
encoded = base64_urlencode(x)
decoded = base64_urldecode(encoded)
print(encoded)
print(decoded)
