base64

nimony/lib/std/base64.nim

Base64 encoder/decoder (RFC 4648).

encode produces standard base64 by default, or the URL- and filename-safe alphabet (-/_ instead of +//) when safe = true. decode accepts either alphabet and ignores = padding and whitespace.

func encode(s: openArray[T]; safe: bool): string
Encodes s (a sequence of chars or bytes) to a base64 string.
func encodeMime(s: string; lineLen: int64; newLine: string; safe: bool): string
Encodes s to base64 (RFC 2045 MIME): the output is wrapped into lines of at most lineLen characters, separated by newLine.
func decode(s: string): string
Decodes a base64 string (standard or URL-safe) back to the original bytes. = padding and any whitespace/invalid characters are ignored.
