The PRIMAR CD Service using IHO certificate
On this page you can download the latest ENC Base and Update CD. The content of these CDs are encrypted and can only be viewed by compatible systems. In order to meet different users' requirements the CDs are available in two different formats: as zip files and as ISO files.
On each zip and iso file you will find a MD5 checksum. This checksum can be used to verify that your downloaded file is identical to the file on our web. To check the MD5 checksum on your downloaded file you will need a program that can calculate the MD5 checksum, e.g. Md5Checker.
The base CD set contains an encrypted copy of all ENCs available in the PRIMAR service (base and update files) at the time of production. Several CDs are required for full coverage.
The update CD contains an encrypted copy of all ENCs (base and update files) issued since the base CD set was produced. All files are provided on a single CD.
COMPLETE EXHANGE SET
The complete exchange set contains an encrypted copy of all ENCs available in the PRIMAR service (base and update files) at the time of production. The complete exchange set will be available on a weekly basis and on the same interval as the update CD.
DELTA EXCHANGE SET
