The Encrypted Pattern

The encrypted pattern turns unusable!

If the pattern was encrypted only for this machine it will be unusable after deleting the machine key or after expiration of its validity.

Store the unencrypted pattern by all means.

Only delete the machine key if no corresponding pattern is to be knitted on this machine.

Encrypt the pattern again if necessary.

The encrypted pattern cannot be decrypted anymore!

If the pattern was encrypted it will be unusable after deleting the machine key or after expiration of the validity.
Even Stoll is not able to decrypt an encrypted pattern anymore!

Store the unencrypted pattern by all means.

Send the unencrypted pattern with the log file to Stoll if necessary.
