![]() This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. All line separators or other characters not found in the base64 alphabet table are ignored in decoding operation. No line separator is added to the end of the encoded output. The encoded output must be represented in lines of no more than 76 characters each and uses a carriage return '\r' followed immediately by a linefeed '\n' as the line separator. It uses the Base64 alphabet as specified in RFC 2045 for encoding and decoding operations. The decoder rejects data that contains characters outside the base64 alphabet. The encoder does not add any line separator character. It uses the Base64 alphabet specified by Java in RFC 4648 for encoding and decoding operations. It uses the Base64 alphabet specified by Java in RFC 4648 and RFC 2045 for encoding and decoding operations. You can use these methods at the following levels. This class provides three different encoders and decoders to encrypt information at each level. You need to import 64 in your source file to use its methods. You can encrypt and decrypt your data by using provided methods. Java provides a class Base64 to deal with encryption. Next → ← prev Java Base64 Encode and Decode let base64EncodedData = base64EncodedString.data(using. The initialization fails if the base64 encoded string is invalid. The initializer is failable, so we use optional binding to unwrap it. We use the Data object to create another Data object by passing it to init(base64Encoded:) initializer. ![]() To decode the base64 encoded string, we convert the string to a Data object by calling data(using:) on the String object. The value stored in the base64EncodedString constant is what you would receive from, for example, an API. ![]() Let base64EncodedString = stringData.base64EncodedString() Second, we ask the Data object for its base64 encoded string representation by invoking its base64EncodedString(options:) method. First, we convert the string to a Data object by calling data(using:) on the String object. We convert the value stored in the string constant to a base64 encoded string in two steps. Let's start with a string and base64 encode it. Base64 Encodingįire up Xcode and create a playground by choosing the Blank template from the iOS > Playground section if you want to follow along.Īdd an import statement for Foundation. Data is base64 encoded to ensure data integrity, making it more likely the data remains intact when it is sent from point A to point B, for example, from a server to your application. While you and I cannot read base64 encoded data, it is trivial for a computer to decipher base64 encoded data.īase64 encoding converts binary data to ASCII ( American Standard Code for Information Interchange) characters. I want to start off by emphasizing that base64 encoding is not form of encryption and it shouldn't be used to protect data. In this episode, I show you how easy that is using Swift. It is the task of your application to base64 decode it. The data your application receives from a remote API may be base64 encoded.
