Bitcoin core encrypts your private keys with a random key. This random key is encrypted (AES-256-CBC) with a key derived from your passphrase.</p>

You cannot. The passphrase is not stored directly in the wallet. It is directly used as an encryption key.

No it is not possible to find the passphrase with a hex editor.
Bitcoin core encrypts your private keys with a random key. This random key is encrypted (AES-256-CBC) with a key derived from your passphrase.

If you remember something from the key (parts of it, letters, even length) you need a program that permutates what you know. If not you can try brute force starting with 1 character and up. Unfortunately when you chose a good key (length>15 characters) this is a near impossible task.
