Class Base64Codec

java.lang.Object

com.licensespring.utils.Base64Codec

public final class Base64Codec
extends Object

Utility class for Base64 encoding and decoding operations. Provides a unified interface for Base64 operations across the application and ensures proper padding handling.

This implementation uses java.util.Base64 as the standard implementation, with explicit padding handling to ensure consistency.

Method Detail

encodeToString

public static String encodeToString(byte[] data)

Encodes a byte array to a Base64 string with proper padding.

Parameters:

data - The bytes to encode

Returns:

Base64 encoded string with proper padding

encodeToString

public static String encodeToString(String data)

Encodes a string to a Base64 string with proper padding.

Parameters:

data - The string to encode

Returns:

Base64 encoded string with proper padding

encodeToBytes

public static byte[] encodeToBytes(byte[] data)

Encodes a byte array to a Base64 byte array. This is useful for binary operations where you need the encoded bytes directly.

Parameters:

data - The bytes to encode

Returns:

Base64 encoded byte array

decode

public static byte[] decode(String data)

Decodes a Base64 string to a byte array, handling padding automatically.

Parameters:

data - The Base64 string to decode

Returns:

The decoded bytes

decodeToString

public static String decodeToString(String data)

Decodes a Base64 string to a UTF-8 string, handling padding automatically.

Parameters:

data - The Base64 string to decode

Returns:

The decoded string

ensureProperPadding

public static String ensureProperPadding(String data)

Ensures that a Base64 string has proper padding. Base64 encoding requires the length to be a multiple of 4. If it's not, padding characters ('=') are added.

Parameters:

data - The Base64 string that may need padding

Returns:

A properly padded Base64 string
