authentication to a sha256_password account fails over SSL

[weigon]

Description

The following code:

mysql --user=root -e "CREATE USER sha256_19 IDENTIFIED WITH sha256_password BY '0123456789012345678'"
php -r 'mysqli_real_connect(mysqli_init(), "127.0.0.1", "sha256_19", "0123456789012345678", "", 6000, "", MYSQLI_CLIENT_SSL);' // throws

Resulted in this output:

PHP Fatal error:  Uncaught mysqli_sql_exception: Access denied for user 'sha256_19'@'localhost' (using password: YES) in Command line code:1
Stack trace:
#0 Command line code(1): mysqli_real_connect()
#1 {main}
  thrown in Command line code on line 1

But I expected this output instead:

Without forcing SSL it works:

php -r 'mysqli_real_connect(mysqli_init(), "127.0.0.1", "sha256_19", "0123456789012345678", "", 6000, "");'

PHP Version

PHP 8.1.2

Operating System

Ubuntu 22.04

Seems like an off-by-one in mysqlnd_sha256_auth_get_auth_data in the conn->vio->data->ssl case. If I add a NUL byte, then it works...
EDIT: this used to be a bug in another piece of code as well. Okay this seems simple to resolve.
