Examples of creating base64 hashes using HMAC SHA256 in different languages 21 Oct 2012. Let’s give it a go with Swift. encodeToString(originalInput. The Base64 encoding represents every 6 bits of the binary input with one ASCII character. When you use other encodings, it is not safe to force-unwrap (unless you explicitly know that a string is guaranteed to be representable). The Windows Data Protection API (DPAPI) is a great technology to securely encrypt user or machine specific data without having to worry about an encryption key. getEncoder(). To write the JSON data in a string that spans multiple lines, use a multiline string literal delimited by triple quotes, a feature that was introduced in Swift 4.
