   SSLPost Security Features


SSLPost uses Secure Sockets Layer (SSL) protocols with a 128-bit key to encrypt communication with the server. The Advanced Encryption Standard (AES) algorithm is used with a 128-bit key to encrypt messages. AES and SSL are recognised as highly secure algorithms when used with a 128-bit key.


Further security features of SSLPost are listed below:


  • SSLPost uses a highly secure encryption wrapper to securely deliver by email any type of digital content to authorised and registered recipients.
  • SSLPost emails include a fingerprint or seal that establishes the time and date that the email was sent and that the email has not been tampered with during its transmission.
  • All access attempts are recorded and sealed thereby preventing the audit log from being tampered with.




   HMRC Compliance


The SSLPost solution meets the requirements set out in the HM Revenue and Customs notice for electronic invoicing. SSLPost guarantees the authenticity of the origin and the integrity of the invoice data by using an "advanced electronic signature" as set out by HMRC.


The HMRC definition of an advanced electronic signature is as follows:


  • Uniquely linked to the signatory.
  • Capable of identifying the signatory.
  • Created using means that the signatory can maintain under his sole control.
  • Linked to the data to which it relates in such a manner that any subsequent change to the data is detectable.
