Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

See more Encryption Examples

Demonstrates how to calculate a hash for a file's contents. Swift

func chilkatTest() {
    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let crypt = CkoCrypt2()!

    // Set the name of the hash algorithm.
    // Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
    crypt.hashAlgorithm = "md5"

    // EncodingMode specifies the encoding of the hash output.
    // It may be "hex", "url", "base64", or "quoted-printable".
    crypt.encodingMode = "hex"

    // Files of any type may be hashed -- it doesn't matter
    // if the file is binary or text...
    var hashStr: String?
    hashStr = crypt.hashFileENC(path: "/temp/something.dat")
    if crypt.lastMethodSuccess != true {
        print("\(crypt.lastErrorText!)")
        return
    }

    print("\(hashStr!)")
