ASCII / HEX Converter

Converts a string to its hexadecimal representation with the 0x prefix — the format used by MySQL/MariaDB functions like LOAD_FILE().

Why#

Some SQL injection scenarios require passing file paths or strings as HEX literals to bypass filters or avoid quote escaping:

SELECT LOAD_FILE(0x2F6574632F706173737764)

This is equivalent to:

SELECT LOAD_FILE('/etc/passwd')

HEX encoding avoids single quotes entirely, which helps when:

• Quotes are filtered or escaped
• WAF blocks string literals
• You need to pass binary data
