This module implements a base64 encoder and decoder.
Encoding data
In order to encode some text simply call the encode procedure:
import base64 let encoded = encode("Hello World") echo(encoded) # SGVsbG8gV29ybGQ=
Apart from strings you can also encode lists of integers or characters:
import base64 let encodedInts = encode([1,2,3]) echo(encodedInts) # AQID let encodedChars = encode(['h','e','y']) echo(encodedChars) # aGV5
The encode procedure takes an openarray so both arrays and sequences can be passed as parameters.
Decoding data
To decode a base64 encoded data string simply call the decode procedure:
import base64 echo(decode("SGVsbG8gV29ybGQ=")) # Hello World
Procs
proc encode[T: SomeInteger | char](s: openArray[T]; lineLen = 75; newLine = "\c\n"): string
-
encodes s into base64 representation. After lineLen characters, a newline is added.
This procedure encodes an openarray (array or sequence) of either integers or characters.
Source Edit proc encode(s: string; lineLen = 75; newLine = "\c\n"): string {...}{.raises: [], tags: [].}
-
encodes s into base64 representation. After lineLen characters, a newline is added.
This procedure encodes a string.
Source Edit proc decode(s: string): string {...}{.raises: [], tags: [].}
- decodes a string in base64 representation back into its original form. Whitespace is skipped. Source Edit
