encode64: Base64 encoding and decoding

In storr: Simple Key Value Stores

Description

Base64 encoding. By default uses the RFC 4648 dialect (file/url encoding) where characters 62 and 63 are "-" and "_". Pass in "+" and "/" to get the RFC 1421 variant (as in other R packages that do base64 encoding).

Usage

encode64(x, char62 = "-", char63 = "_", pad = TRUE)

decode64(x, char62 = "-", char63 = "_", error = TRUE)

Arguments

x	A string or vector of strings to encode/decode
char62	Character to use for the 62nd index
char63	Character to use for the 63rd index
pad	Logical, indicating if strings should be padded with = characters (as RFC 4648 requires)
error	Throw an error if the decoding fails. If FALSE then NA_character_ values are returned for failures.

Examples

x <- encode64("hello")
x
decode64(x)

# Encoding things into filename-safe strings is the reason for
# this function:
encode64("unlikely/to be @ valid filename")

Example output

[1] "aGVsbG8="
[1] "hello"
[1] "dW5saWtlbHkvdG8gYmUgQCB2YWxpZCBmaWxlbmFtZQ=="
