(Swift) Hash the Contents of a String (SHA256 and other hash algorithms)
Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.
func chilkatTest() {
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
let crypt = CkoCrypt2()!
// Choose the hash algorithm.
// Can be "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
crypt.hashAlgorithm = "sha256"
// The byte representation of the string matters when hashing.
// Tell Chilkat that we want to use the utf-8 byte representation.
crypt.charset = "utf-8"
var hashBytes: NSData
hashBytes = crypt.hashString("They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.")
// Let's examine the hash as a hex string.
let sb = CkoStringBuilder()!
sb.appendEncoded(hashBytes, encoding: "hex")
print("SHA256 hash = \(sb.getAsString()!)")
}
