Utility Functions — b64

Functions to perform common tasks when working with base64 encoded strings.

b64_chunk(encoded, width)

b64_wrap(chunks, newline)

Arguments

encoded: a character vector of base64 encoded strings.
width: a numeric scalar defining the width of the chunks. Must be divisible by 4.
chunks: a character vector of base64 encoded strings.
newline: a character scalar defining the newline character.

Value

b64_chunk() returns a list of character vectors.
b64_wrap() returns a scalar character vector.

Details

b64_chunk() splits a character vector of base64 encoded strings into chunks of a specified width.

b64_wrap() wraps a character vector of base64 encoded strings with a newline character.

Examples

encoded <- encode("Hello, world!")
chunked <- b64_chunk(encoded, 4)
chunked
#> [[1]]
#> [1] "SGVs" "bG8s" "IHdv" "cmxk" "IQ=="
#> 

b64_wrap(chunked, "\n")
#> [1] "SGVs\nbG8s\nIHdv\ncmxk\nIQ=="
