SELS Brochure

Secure Email List Services (SELS) is an open source software for creating and developing secure email list services among user communities. SELS provides signature and encryption capabilities while ensuring that the List Server does not have access to email plain text. SELS has been developed with available open-source components and is compatible with many commonly used email clients.

Current Release

newThe current release is 0.7. Download here.

New Changes

  • new Generate and store Revocation certificate for List Key (LK). The Moderator distributes them manually during key update.
  • new Changed algorithiom CAST5 to AES256 for password based encryption during " user subscribe" in LM.
  • new Removed email address from user key pair. Retain name and comment.
  • new A Subscriber MUST verify fingerprint after importing the List Moderator's key by out of band means. Changed instructions.txt in LM/bin.
Here is the SELS Version History.

Features

  • Two key lengths supported for all SELS keys, 1024 and 2048 bits.
  • Bounce Messages generated for general user errors. See List Subscriber FAQ entry #4
  • User keypair for list in decryption only. This key pair cannot be used for signing or encrypting a message, thus enhacing SELS security.
  • All users are recommended to place full key trust in the List Moderator's public key and then sign it locally with their signature key. This allows transitive trust for all keys signed by List Moderator automatically.
  • List Moderator and List Server Administrator can choose key expiration for their respective keys.
  • Batch user subscription with auto generated passwords.
  • Multiple recipients supported.
  • List Server (LM) , List Moderator (LS), Crypto code (common) and modified GnuPG library (gpglib) available as a Gnu Autotools code archive.

  • Bug 16 fixed in 0.5.5 release.
