ENCODING

encoding Module in Vint

The encoding module in Vint provides functions for encoding and decoding data in various formats. This includes commonly used encoding schemes like Base64.

Importing the encoding Module

To use the encoding module, import it as follows:

import encoding

Functions and Examples

1. Base64 Encoding with base64Encode()

The base64Encode function encodes a string into Base64 format. Base64 encoding is often used for encoding binary data as text, making it suitable for transmission over text-based protocols such as email or HTTP.

Syntax:

base64Encode(inputString)

• inputString: The string you want to encode.

Example:

import encoding

encoded = encoding.base64Encode("Hello, World!")
print(encoded)  // Expected output: "SGVsbG8sIFdvcmxkIQ=="

In this example, the string "Hello, World!" is encoded into Base64 format.

2. Base64 Decoding with base64Decode()

The base64Decode function decodes a Base64-encoded string back into its original format.

Syntax:

base64Decode(encodedString)

• encodedString: The Base64-encoded string that you want to decode.

Example:

import encoding

encoded = encoding.base64Encode("Hello, World!")
print(encoded)  // Expected output: "SGVsbG8sIFdvcmxkIQ=="

decoded = encoding.base64Decode(encoded)
print(decoded)  // Expected output: "Hello, World!"

In this example, the Base64-encoded string is decoded back to its original value.
