Integration with ReactNative

.../Frameworks/ObjectivePGP.framework/strip-frameworks.sh: No such file or directory

How I solve this?

[krzyzanowskim]

Just copy the file to the right place https://github.com/krzyzanowskim/ObjectivePGP/tree/master/scripts

Looks like something went wrong with the automatic script installation. Will address that in next release.

[danielfttorres]

Can I replace this step using cocoa pods? I try to use cocoa pods, but receive this error: Apple Mach-O Linker Error Group. Any ideia? I try to link this project in React Native project.

[krzyzanowskim]

Cocoapods should work.
Not sure what Apple Mach-O Linker Error Group means. There should be more. I'm not a React Native expert, but I can try to build it by my own if you send me the sample project.

[danielfttorres]

Okey, thanks! The example is here: https://github.com/danielfeelfine/react-native-pgp-example

[krzyzanowskim]

It should build at all ?

/Users/marcinkrzyzanowski/Devel/react-native-pgp-example/node_modules/react-native/React/../third-party/glog-0.3.4/src/base/mutex.h:105:10: fatal error: 'config.h' file not found
#include "config.h"           // to figure out pthreads support
         ^
1 error generated.

[danielfttorres]

No. It's an another React Native error. You can solve this with:

In the Terminal, navigate to the react-native/third-party/glog folder inside node_modules (for me, this was cd node_modules/react-native/third-party/glog-0.3.4)
Once actively in this folder, run ../../scripts/ios-configure-glog.sh
Glog is configured and the required config.h header file is created for Xcode to find

what about this:

** BUILD SUCCEEDED **

[danielfttorres]

Select a developer team in General settings of project, ex.:

[krzyzanowskim]

that's not that. Info.plist is not at the location the script think it is.

[danielfttorres]

It's about the first error or about this latest error? In the latest error, you must be select a team and solve the problem.

[krzyzanowskim]

it's that facebook/react-native#10102
the script can't correctly setup path to ios binaries

basically this call

[danielfttorres]

Were you able to compile successfully?

[krzyzanowskim]

ok, figured out. Needed to edit runIOS.js to use correct paths. Where is the problem ?

[danielfttorres]

The problem is strip-frameworks.sh: No such file or directory when compiling after install ObjectivePGP using CocoaPods. Did you use CocoaPods?

[krzyzanowskim]

yes, I used the project you created, fixed react-native and build. Here is the full archive:
https://drive.google.com/open?id=0BzncA1vRoAW_d0ZObVlTUzNvQUU

[krzyzanowskim]

I had to patch runIOS.js script from react-native to use proper paths.

[danielfttorres]

Your project is different from my. My code use ObjectivePGP and your, not. So it worked (I think). Try installing ObjectivePGP and adding the files:

ReactNativePGP.m

#import "ReactNativePGP.h"
#import <React/RCTLog.h>
//#include <ObjectivePGP/ObjectivePGP.h>

@implementation ReactNativePGP

//ObjectivePGP *pgp = [[ObjectivePGP alloc] init];

// To export a module named ReactNativePGP
RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)
{
  RCTLogInfo(@"Pretending to create an event %@ at %@", name, location);
}

@end

ReactNativePGP.h

#import <React/RCTBridgeModule.h>

@interface ReactNativePGP : NSObject <RCTBridgeModule>
@end

[krzyzanowskim]

those files are not part of the Xcode project, how should it work? The cocoapods installed the ObjectivePGP.framework though.

[danielfttorres]

How can I add to my XCode project?

You'd better start a fresh react-native (it's fast) project and try to adding ObjectivePGP in it. And so you could reproduce the problem.

[krzyzanowskim]

How can I add to my XCode project?

drag file to xcode and add to target

You'd better start a fresh react-native (it's fast)

I rather not, it doesn't look like the toolchain is working out of the box.

[krzyzanowskim]

anyway, the cocoapods setup works with ObjectivePGP, here is the current version of the project I build:

https://github.com/krzyzanowskim/react-native-pgp-example

[danielfttorres]

When try to run your fork, I take the same error (commented in https://github.com/krzyzanowskim/ObjectivePGP/issues/70#issuecomment-326370907):

[krzyzanowskim]

What's your Xcode version?

[danielfttorres]

Version 8.3.3 (8E3004b) too.

[krzyzanowskim]

¯_(ツ)_/¯

I'm running with this command:
react-native run-ios
that build the app for the simulator.

[danielfttorres]

Thanks! I BUILD SUCCEEDED too by run react-native run-ios instead of CMD+B in Xcode.

Now I will try to expose the ObjetivePGP methods using iOS Native Modules from react-native, but first, I have some questions:

1. Can I generate a pair of keys and store that into device with OBjetivePGP? How do you think it would be safer? What method I use to this?
2. How long does a device take to generate a key? 1-2 seconds? And how long does it take to sign a message?
3. I can decrypt key and sign a message with that key using ObjetivePGP? What methods I use to this?

[krzyzanowskim]

Can I generate a pair of keys and store that into device with OBjetivePGP? How do you think it would be safer? What method I use to this?

not today. This feature will be available with next update. It's currently WIP.

I can decrypt key and sign a message with that key using ObjetivePGP? What methods I use to this?

If I understand the question right, you just sign with password https://github.com/krzyzanowskim/ObjectivePGP#sign-data-or-file

[danielfttorres]

Do you know if there is any module that generates keys in iOS? Would it be a difficult task to do one or implement this method?

I'm thinking of using: https://github.com/kryptco/kryptonite-ios. What do you think?

Thanks

[krzyzanowskim]

as I said, key generation is in progress ETA in 2 weeks. I'm rather not going to verify the kryptonite compliance.

[danielfttorres]

Great @krzyzanowskim. I will wait for the implementation. In the meantime, I'll be working on the RN wrapper of signature methods.

Thanks
