Depending on your needs or your technical pool,you may need to buy additionnal certificates or licences.

Several configuration can be encountered :

  • Active / Active
  • Active / Inactive
  • Back-up site
  • Several virtual machines on one physical machine

A digital certificate reissue:

A new certificate can be reissued in substitution of an existing one with the same fields but a different pair of keys*.
That can be done in those situations:

  • A certificate loss after a hard disk failure
  • A software switching
  • The modification of the key sizes
  • The vulnerability of the privet key
  • The upgrating of the signature from MD5 to SHA1

*pair of keys : Item privet key / public key elements : if a new pair of keys is needed a new CSR has to be requested.
