Generating base64-encoded Authorization headers in a variety of languages

Line 7 correction for jquery snippet: "Authorization", "Basic " + btoa(username + ":" + password)

PowerShell

$username = 'test'
$password = 'password'
$base64AuthInfo = [convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1} -f $username, $password")))
$base64AuthInfo

The code above doesn't work. Below is the fix.

$username = 'test'
$password = 'password'
$base64AuthInfo = [convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("${username}:${password}")))
$base64AuthInfo

Scala:

val bytesFromString = (username ++ ":" ++ password).getBytes("UTF-8")
val urlAuth = "Basic " ++ Base64.encode(bytesFromString)

The right scala implementation which run directly :

  val tokenBytes = s"$username:$password".getBytes("UTF-8")
  val tokenB64 = new String(java.util.Base64.getEncoder.encode(tokenBytes))
  val token = s"Basic $tokenB64"

in JQuery, aren't we missing the 'Basic ' prefix?

in Rust;

use http_auth_basic::Credentials;

let credentials = Credentials::new("username", "password").as_http_header();

assert_eq!(String::from("Basic dXNlcm5hbWU6cGFzc3dvcmQ="), credentials);

In Elixir:

username = "username"
password = "password"

"#{username}:#{password}"
|> Base.encode64()

In kotlin:

val username = "username"
val password = "password
val userpass = username + ":" + password
val encodedAuth = encodeToString(userpass.toByteArray(), NO_WRAP)
val authHeaderValue = "Basic " + encodedAuth
httpURLConnection.setRequestProperty("Authorization", authHeaderValue)

In Salesforce APEX

HttpRequest request = new HttpRequest();
String username = 'test';
String password = 'test';

String accessToken = EncodingUtil.base64Encode(Blob.valueOf(username + ':' + password));
request.setHeader('Authorization', 'Basic ' + accessToken);

In oracle pl/sql

set serveroutput on;
DECLARE
v_str VARCHAR2(1000);
BEGIN
--Create encoded value
v_str := utl_encode.text_encode('Testuser:verySecret','WE8ISO8859P1', UTL_ENCODE.BASE64);
dbms_output.put_line(v_str);
--Decode the value..
v_str := utl_encode.text_decode(v_str,'WE8ISO8859P1', UTL_ENCODE.BASE64);
dbms_output.put_line(v_str);
END;
/

or

select utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw('Testuser:verySecret')))
  from dual;
/
