digest.base64

STRINGdigest.base64STRINGinput

Available in all subroutines.

Returns the Base64 encoding of the input string, as specified by RFC 4648 and is suitable for decoding by digest.base64_decode.

The alphabet used is:

ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
0123456789+/

The output string is padded to a multiple of four characters in length using the = character.

See digest.base64_decode for details on the structure of Base64 encoding. In particular, note that it is possible for two input strings to encode to the same Base64 string.

Example

declare local var.base64_encoded STRING;
set var.base64_encoded = digest.base64("Καλώς ορίσατε");
# var.base64_encoded is now "zprOsc67z47PgiDOv8+Bzq/Pg86xz4TOtQ=="
