original: The encryption key is trivially related to the decryption key, in that they may be identical or there is a simple transform to go between the two keys.
simplifications: The encryption key is trivially related to the decryption key.  They may be identical or there is a simple difference between the two keys. the locked security key is not like the unlocked security key, if you are thinking they may be the same or that it would be easy to change between the two of them The encryption key is connected to the decryption key. They may even be the same or can easily change into the other. The encryption key and decryption key may be identical in function or there is a piece between them. The encryption key is trivially related to the decryption key. They may be identical or there is a simple transform to go between the two keys. The encryption key is trivially related to the decryption key, For instance, they may be the same, or there is a simple transform to go between the two keys. The encryption key is lightly related to the decryption key. They may be identical. There may be a simple transform to go between the two keys. The encryption key may be identical to the decryption key or there may be only a small difference between them. The encryption key is related to the decryption key in that they may be the same or an easy go between to use the two keys The encryption code is slightly related to the decryption key, in that they may be identical or there is a simple transform to go between the
