Base64 Encode Data in Objective-C

Hi Guys,

I need to encode data in an objective-c application and I am using base64 encoding to encode the data. But I am not able to find the header files openssl/bio.h and openssl/evp.h. And if I add libcrypto.dylib library in my project then I am getting the error of library not found.

Please let me know if anybody knows how can I get the openssl package to encode the data.

Thanks in advance,
Ishita

Did you add -lssl -lcrypto to "Other Linker Flags" property?

So please let me know how can I do that.

Hi,

Yes I found the Other Linker Flags property and If I add "-lssl -lcrypto" to this property then its giving the error "Library not found for -lssl".

Thanks,
Ishita

Is there a libssl.dylib that you can add to your project?

Sorry for the "me, too" post, but I have a similar need to import certain openssl header files. I have some code that does

#include <openssl/bio.h>

that results at compile time in:

error: openssl/bio.h: No such file or directory

I actually have this file on my system in /usr/include/openssl/bio.h, and I would have assumed that XCode would have found it without further ado, but ...

I'm an XCode newcomer. Can someone please provide information on how to configure the project to find these header files?

Thank you.

So has anybody solved this problem yet? if so it would be nice if somebody could post what they did.
-I added the linker flags, and nothing changes (don't even get an error).
-I tried to add under frameworks the existing files of libcrypto, or libssl, but neither of those do anything. They are just written in red and don't change anything.

If anybody could post some information it would be great.

I don't have the code anymore but it wasn't too much work to write an Obj-C base64 encoder/decoder. My issue with it was that for large audio files it was too slow so I just post NSData directly to my server now. Google it and you should find some other implementations in both C and C++. I tried a bunch and they all worked just not for me case.
