@ -128,13 +128,7 @@ Since SEIPD version 1 is susceptible to downgrade attacks under certain scenario
``` ```
To decrypt the contents of a version 1 SEIPD packet, the session-key obtained in the previous step is used. To decrypt the contents of a version 1 SEIPD packet, the session-key obtained in the previous step is used.
The cipher algorithm is determined by TODO. The cipher algorithm is either extracted from the decrypted session-key (the algorithm ID is typically prefixed to the decrypted session-key), or - in case of a SKESK packet using the direct-method - taken from the SKESKs cipher algorithm field.
```{admonition} TODO
:class: warning
Describe in detail, how the cipher algorithm is obtained.
```
Once the cipher is initialized, the whole encrypted data from the SEIPD packet is decrypted. Once the cipher is initialized, the whole encrypted data from the SEIPD packet is decrypted.
