The following examples provide various scenarios of hash calculation: NET, refer to Microsoft Documentation > SHA512 Class. PayU is not responsible for any security breaches (including any data breaches) that may occur due to non-implementation of the aforesaid security features at your end or any loss or damage arising therefrom to you or any third party. Parameters such as transaction ID and amount need to be verified with the values sent in the request by you. This will identify any of the parameters that have been tampered with in response. Note: It is strongly recommended that you verify the parameters posted by PayU in response to that of the parameter sent by you in the request. Invoice Completion URLs configured with the merchant account.Notification URLs configured with the merchant account.URLs shared as part of payment request to PayU in the parameters: surl, furl, curl, nurl, and termUrl.The last web address accessed by a browser before loading PayU’s checkout page.The following are considered sources for the merchant-level URL: The details including - but are not limited to - the following are considered sensitive information:Īlong with the request, the sensitive information should not be a part of any merchant-level URL. You need to ensure that sensitive information related to the integration is not part of the payment request to PayU. For more information on the integration process, refer to Transaction Details APIs and Webhooks. PayU strongly recommends that you secure your integration by implementing Verify web service and webhook/callback as a secondary confirmation of the transaction response. Computing hash will protect you from any tampering by your customers and help in ensuring a safe and secure transaction experience. Integration SecurityĪfter receiving a response from PayU and comparing it with the request, you must compute the hash (or checksum) again and post-back parameters. For example, if you are not posting udf1, the udf1 field will be left empty in the hash calculation. But, the udf parameters (udf1-udf5) are optional, and you need to calculate the hash based on whether you are posting a particular udf or not. Hence, these parameters cannot be empty in the hash calculation. Here, the following parameters are mandatory:

The parameter order is in the following code block: sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT)Īll the parameters (and their descriptions) mentioned in the above code block have already been mentioned earlier in the Hosted Checkout Integration sections. Note: Ensure that you use pipe (|) character between these parameters as mentioned in the following code block. You need to generate a string using certain parameters and apply the SHA-512 algorithm to this string. PayU uses the SHA-512 hash function that belongs to the SHA-2 family of cryptographic functions. The hash is used to protect transactions against a “man-in-the-middle-attack.” Please let me know your feedback in the response section.Hash Generation Logic for Payment RequestĪ hash is an encrypted value (checksum) that is sent by you in a payment request and sent by PayU in the payment response.

Other options - openssl passwd - help Usage: passwd Valid options are: -help Display this summary -in infile Read passwords from file -noverify Never verify when reading password from terminal -quiet No warnings -table Format output as table -reverse Switch table columns -salt val Use provided salt -stdin Read passwords from stdin -6 SHA512-based password algorithm -5 SHA256-based password algorithm -apr1 MD5-based password algorithm, Apache variant -1 MD5-based password algorithm -aixmd5 AIX MD5-based password algorithm -crypt Standard Unix password algorithm (default) -rand val Load the file(s) into the random number generator -writerand outfile Write random data to the specified file
Method 2- Using openssl passwd -6 Password: Verifying - Password: $6$SX8O9xVd1d/WX2hm$vh9RI2WCnh1BKwmHU2QHX5/ZMwH45zLpVe5v7EykPvjtiNGeYqje9GH2l/dZruVP0kYyPecJRGz1XfYpLERHh0 If TYPE is ‘help’, available methods are printed. If no SALT is specified, a random one is generated. m, - method=TYPE select method TYPE -5 like - method=md5 -S, - salt=SALT use the specified SALT -R, - rounds=NUMBER use the specified NUMBER of rounds -P, - password-fd=NUM read the password from file descriptor NUM instead of /dev/tty -s, - stdin like - password-fd=0 -h, - help display this help and exit -V, - version output version information and exit If PASSWORD is missing then it is asked interactively. Other Options - mkpasswd - help Usage: mkpasswd … ] Crypts the PASSWORD using crypt(3).
