DGSecurityCrypto

Cryptography contents

• You can build a dynamic framework via the DGSecurityCrypto target.

• You can test the codes via the DGSecurityCryptoTests target.

Usage

For iOS 8 and later, you can use dynamic framework. (The deployment target greater than or equal to 8.0.0.)

For iOS 6 and later, you can add the source codes to project. (The deployment target less than 8.0.0.)

If an error occurs：Include of non-modular header inside framework module ***

You can set Allow Non-modular Includes In Framework Modules to YES (In TARGETS -> Build Settings -> Language - Modules)

You may should add -ObjC to TARGETS -> Build Settings -> Linking -> Other Linker Flags.
