Cryptographic library written in Swift
DulocCastle
DulocCastle is a general cryptographic library written in Swift.
I was looking for a nice cryptographic library that easily interfaces with Apple CommonCrypto and Keychain. I couldn’t find anything that really got the job done so I’ve decided to take a crack at it myself.
The intention of this library is that it will not depend on any other libraries and will be fully self contained. It will be a fully loaded PKI library that will support the most common cryptpgraphic structures and functions.
A lot of inspiration for the creation of this library was BouncyCastle in Java and it’s lack of existence in Swift.
