    Authorize.Net is phasing out the MD5 based hash use for transaction response verification in favor of the SHA-512 based hash utilizing a Signature Key.The end of support for MD5 Hash will be done in two phases:
    Phase 1 - As of February 11, 2019 have removed the ability to configure or update MD5 Hash setting in the Merchant Interface. Merchants who had this setting configured have already been emailed/contacted.
    Phase 2- Stop sending the MD5 Hash data element in the API response. To continue verifying via hash will require applications to support the SHA-512 hash via signature key.
    • Sandbox has been updated as of March 7, 2019 to stop populating the MD5 Hash value, but the field will still be present but empty.
    • Production has been updated as of June 27, 2019 (10:30am PT) to stop populating the MD5 Hash value. The field will still be present but empty.
      When you receive a transaction response from Authorize.Net, it includes a SHA2 hash element; the name and position depend on the API integration method used. The SHA2 field contains HMAC-SHA512 hash that Authorize.Net generated for the transaction and can be used to validate the response received from Authorize.Net but is not required to do so.
  14. To obtain ‘Signature key’ follow the same process  from Point 6 to 12  but select ‘new signature key’ instead of ‘new transaction key’ . Signature key generation process.This signature key needs to be added instead of Md5 hash into the system once implemented in the system.
