Created page with "==Fulll Title== Distinguished Encoding Rules (DER) we created to allow a centralized structure for digital representation of real-word entities such as entries in a teleph..."

New page

==Fulll Title==
[[Distinguished Encoding Rules]] (DER) we created to allow a centralized structure for digital representation of real-word entities such as entries in a telephone directory.

==Context==
The rules were created by the ITU

+The encoding rules are defined by the ITU standard S.690 which defines BER, CER and DER. Only DER has seen broad adoption in the [[Public Key Infrastructure]] used for TSL and other certificates. This is because BER and others give the developers options about encoding while DER does not. That makes it possible for a DER signed object to be deconstructed and reconstrued and will have the same hash and hence the same signature.
