Sqlite_open file is encrypted

Obviously in hindsight, opening foobar. I had the same error when I was trying to access a db dump in another system compared to compared to where it was obtained. When I tried to open on a dev machine, it threw the reported error in this thread:.

This turned out to be due to the differences in the sqlite version between those systems. This dev system version was 3. The version on the production system was 3. Once I had the sqlite3 upgraded to same version, I was able to access all its data. I am just showing below the tables are displayed as expected:. Your database did not become encrypted this is only one of the two options in the error message.

Your data recovery tool did not recover the correct data; what you have in the file is something else. The issue is with sqlcipher version upgrade in my case, Whenever I update my pod it automatically upgrade the sqlcipher and the error occurred. For a quick fix just manually add the SDK instead of Pod install. And for a proper solution use this link GitHub Solution.

You could use the sqlite browser to dump the database to SQL, at least then you could see what's in there and load it back to sqlite, hopefully in a way that lets you open it from Python.

That worked: exporting to sql and then importing again. Python will open that. Add a comment. Active Oldest Votes. Improve this answer. Sign up or log in Sign up using Google. Sign up using Facebook.

If you specify a key that is larger than the maximum key length, then the excess key material is silently ignored. For the "-textkey" option, up to bytes of the passphrase are hashed using RC4 and the hash value becomes the encryption key.

Note that in this context the RC4 algorithm is being used as a hash function, not as a cryptographic function, so the fact that RC4 is a cryptographically weak algorithm is irrelevant. The prefix must be exactly one of "rc4:", "aes", or "aes". The prefix is not used as part of the key sent into the encryption algorithm.

So the real key should begin on the first byte after the prefix. Take note of the following important details: The prefix is case sensitive. If the key prefix is omitted or misspelled, then the encryption algorithm defaults to "aes" and the misspelled prefix becomes part of the key.

The algorithm prefix strings work on the "sqlite-see. For any of SEE implementations, any prefix on the key is interpreted as part of the key.

Without a nonce, the encryption can be broken using a chosen-plaintext attack. Purists will argue rightly that the encryption is weak without a nonce. The number of bytes of nonce on each page of the database is determined by byte 20 of the database file. This value is set to zero by default in databases created by the public-domain version of SQLite. You can check the size of the nonce for a database by using the ". The output of the ".

Thus, you can always check to see how much nonce is being used, even on an encrypted database file, just by looking at byte It is recommended that any product that uses encryption check this byte to make sure it is being set to 4 or 12 or 32 and not 0. The nonce should be at least 12 bytes.

Use the SEE-enabled CLI to read an encrypted database, but change the last character of the supplied key by a single character value.

Verify that a minor change to the end of the key like this renders the database unreadable. The error message should be "file is not a database". Repeat this test with multiple variations of the key. Confirm that the database is only accessible if the key is exactly correct. Try to compress an encrypted database file and verify that the file is uncompressible.

In other words, run a program like "zip" or "gzip" against the encrypted database and verify that compression does not change the size of the file more than a few bytes smaller. Limitations TEMP tables are not encrypted. In-memory ":memory:" databases are not encrypted. Bytes 16 through 23 of the database file contain header information which is not encrypted.

The key to encryption is a combination of the page number, the random nonce if any and the database key. The data is encrypted in both the main database and in the rollback journal or WAL file but is unencrypted when held in memory. Post as a guest Name. Email Required, but never shown.
