Hey,can you show me your sqlcipher version. is it for commercial edition?

I tried your code.But I stucked at decrypt phase:

[Error: near line 5: file is encrypted or is not a database]

It looks like the sqlcipher I use not able to decrypt. I tried it in my Mac and Ubuntu server, same error. Wish you show me the point. ^.^

Me too, the same error occured in my case. Does wechat(v6.3.13) change the PRAGMA?
