Just installed SQLCipher with cocoapods and is trying to encrypt an existing sqlite db using sqlite3_rekey_v2(). However while tracing it seems that it gets to this condition. I was under the impression that if a database is not encrypted calling sqlite3_rekey_v2 will encrypt it in-place. if(ct…

I was able to get a legit encrypted database and I’m able to open it using DB Browser for SQLite on OSX providing the encrypted passphrase. But when I try to decrypt in objective-c it always comes up as invalid. I’m getting error code 26. Do I have a build issue? const char* key = [self.…

Hi @dannyl07 Thanks for your interest in SQLCipher and for posting to the discussion forum. [image] dannyl07: trying to encrypt an existing sqlite db using sqlite3_rekey_v2(). However while tracing it seems that it gets to this condition. I was under the impression that if a database is not en…

Hi, Thank you for responding. The database was encrypted by me. By ATTACH …filepath AS encrypted KEY …passphrase and then SELECT sqlcipher_export(‘encrypted’); I’m able to open it with DB Browser for SQLite by providing the correct password. The DB Browser setting is “SQLCipher 4 defaults”, usi…

@dannyl07 Are you including separate sqlite3 dependencies within your non-bare-bones project (potentially from other cocoa pods)? Please see the note on this documentation page under Cocoa pods integration: SQLCipher Community Edition - iOS and macOS Tutorial - Zetetic

I think I am including separate sqlite3 dependencies inadvertently. I just deleted my pod folder and did a pod install, and now my project doesn’t compile. I’m getting “redefinition of sqlite3_…” errors. It shows the previous definition is in “iPhoneSimulator.sdk/usr/include/sqlite3.h”. I am u…

@dannyl07 We don’t maintain that project (SQLite.swift), but if you’re still experiencing difficulties I would recommend incrementally adding each of your pod dependencies to a bare-bones project to see if you’re able to reproduce the issue there. Since you mentioned previously that you were able t…

Hi @mmoore , Thanks for your suggestion. I did that and found two culprits: pod ‘CouchbaseLite-Swift-Enterprise’, ‘~> 2.8’ pod ‘Firebase/Analytics’ Couchbase is a nosql database for mobile apps and Firebase is Google Analytics. Both uses sqlite underneath the hood. Is there something I’m missi…

@dannyl07 [image] dannyl07: Is there a workaround for them to operate together? You can have a look at my post here: Cannot open encrypted database with SQLCipher 4 - #4 by mmoore

@mmoore Thank you. I think I finally figured out that an additional step is to modify the “Other Linker Flags” and ensure I insert -framework “SQLCipher” as the first item before $(inherited). That was the only way I can get all of this to work. Thanks
