util.Strings.base64EncodeFromHexString

Converts the hexadecimal string passed as parameter to a Base64 encoded string.

Syntax

util.Strings.base64EncodeFromHexString(
  s STRING
 )
  RETURNS STRING

s is the source hexadecimal string to convert in Base64.

Usage

The util.Strings.base64EncodeFromHexString() method first converts the hexadecimal string passed as parameter to an array of bytes, then it converts the array of bytes to a Base64 representation, and returns the resulting Base64 encoded string.

Tip:

Use the util.Integer.toHexString() method to build an hexadecimal string from a set of integer/byte values, then convert the hexadecimal string to a Base64 representation.

Example

IMPORT util
MAIN
    DEFINE hexa VARCHAR(50)
    DISPLAY util.Strings.base64EncodeFromHexString( "00" )
    DISPLAY util.Strings.base64EncodeFromHexString( "0000" )
    DISPLAY util.Strings.base64EncodeFromHexString( "FFFF" )
    DISPLAY util.Strings.base64EncodeFromHexString( "42EFB3E5" )
    LET hexa = util.Integer.toHexString(65)
            || util.Integer.toHexString(66)
            || util.Integer.toHexString(67)
    DISPLAY hexa
    DISPLAY util.Strings.base64EncodeFromHexString( hexa )
END MAIN

Output:

AA==
AAA=
//8=
Qu+z5Q==
414243
