Hash Calculation

The request sent for many transaction types should include the PG-Auth-Token in the header information. The PG-Auth-Token consists of the values "MerchantNumber:TerminalNumber:Hash".

When calculating the hash here, the merchantNumber, terminalNumber, and secretKey information belonging to the merchant are hashed with sha256 and converted to a string.

public class SHA256Example {\n public static String sha256(Long merchantNumber, Long terminalNumber, String secretKey) {\n String text = merchantNumber.toString() + terminalNumber.toString() + secretKey;\n try {\n MessageDigest digest = MessageDigest.getInstance(\"SHA-256\");\n byte[] hash = digest.digest(text.getBytes(StandardCharsets.UTF_8));\n String sha256Hex = DatatypeConverter.printBase64Binary(hash);\n return sha256Hex;\n } catch (NoSuchAlgorithmException e) {\n e.printStackTrace();\n return null;\n }\n }\n}
