Joel’s Writings » Compute MD5 or SHA hash of large file efficiently on iOS and Mac OS X
Computing cryptographic hashes of files on iOS and Mac OS X using the CommonCrypto APIs is fairly easy, but doing it in a way that minimizes memory consumption even with large files can be a little more difficult… The other day, I was reading what some people were saying about this on a forum about iPhone development, and they thought they found the trick, but they still had a growing memory footp
Can't convert NSData to NSString in swift
This is my function. First println print correct hash to console but in the next row program crashes. Can you help me? func sha256(string: NSString) -> NSString { var data : NSData! = string.dataUsingEncoding(NSUTF8StringEncoding) var hash = [UInt8](count: Int(CC_SHA256_DIGEST_LENGTH), repeatedValue: 0) CC_SHA256(data.bytes, CC_LONG(data.length), &hash) let res = NSData(bytes: hash, length: Int(CC
