Is it possible to decrypt a file without knowing password only an encrypted string?

Question

I am stuck at a point, here I have encryptionkeys.db(i don't know the use of a file). The folder name is also encrypted(coded) I know the folder name(decrypted), with this I just want to get the password and decrypt the simultaneous files.

Answer 1

It depends if the encryption method used is vulnerable to a Known-plaintext attack. If so, it may be possible to retrieve the encryption keys, but this is unlikely as standards such as AES are resistant to this.
