mysql_laravel_decrypt.sql

CREATE DEFINER=`%`@`%` FUNCTION `LARAVEL_DECRYPT`(
	`encstr` TEXT,
	`raw_key` VARCHAR(255)

)
RETURNS varchar(255) CHARSET utf8 COLLATE utf8_unicode_ci

COMMENT ''
BEGIN

		DECLARE decrypted VARCHAR(255);
		
		SET decrypted = AES_DECRYPT(FROM_BASE64(JSON_UNQUOTE(JSON_EXTRACT(CONVERT(FROM_BASE64(encstr) USING utf8), '$.value'))), FROM_BASE64(raw_key), FROM_BASE64(JSON_UNQUOTE(JSON_EXTRACT(CONVERT(FROM_BASE64(encstr) USING utf8), '$.iv'))));
		SET decrypted = SUBSTRING_INDEX(decrypted, ':', -1);

This is more portable version that works in MySQL and MariaDB >= 11.2
