Base64 encode and Base64 decode tool

Base64 encoding is a method of representing binary data as ASCII text. It's commonly used for encoding data in a way that can be easily transmitted over text-based protocols, such as email or web services, and stored in text-based file formats, such as XML or JSON.

In Base64 encoding, binary data is divided into groups of 6 bits, and each group of 6 bits is mapped to a unique 64-character alphabet. This alphabet consists of the upper- and lowercase letters A-Z, the digits 0-9, and two special characters: + and /. The = character is used as a padding character to ensure that the last group of 6 bits has a length of 4 bits.

To encode data in Base64, the binary data is first divided into groups of 6 bits, and each group is then mapped to a unique character in the 64-character alphabet. The resulting string of characters is the Base64 encoded representation of the original binary data.

To decode Base64 encoded data, the reverse process is followed. The Base64 encoded string is first divided into 4-bit groups, and each group is then mapped back to its original 6-bit binary representation. The resulting binary data is the decoded representation of the original Base64 encoded string.

Base64 encoding is widely used for encoding binary data in a way that is easily transmitted over text-based protocols and stored in text-based file formats. It's also commonly used for encoding authentication credentials, such as username and password, in HTTP Basic Authentication headers.

A Base64 encoder is a tool or software that can be used to convert binary data into its Base64 representation. The encoding process involves dividing the binary data into groups of 6 bits and mapping each group to a unique character in the 64-character alphabet. The resulting encoded string is typically longer than the original binary data, but it can be stored, transmitted, or processed as text, which is a more convenient format for many applications.

Base64 encoders are commonly implemented in various programming languages and can be used as part of a larger software application or as a standalone tool. Many programming languages have built-in support for Base64 encoding and decoding, so you can easily implement Base64 encoding in your application using just a few lines of code.

Base64 encoders are widely used in a variety of applications, including email attachments, image storage, and encryption algorithms, among others. They are also commonly used in web applications, where Base64 encoded data can be used to transmit binary data over HTTP without the need for additional encoding or decoding.

A Base64 decoder is a tool or software that can be used to convert Base64-encoded data back into its original binary format. The decoding process involves mapping each character in the encoded string back to its corresponding 6-bit binary representation and then reassembling the resulting binary data into its original format.

Using an online Base64 encoder is straightforward and requires just a few steps:

1. Go to mojha's online Base64 encoder tool.
2. Copy and paste the binary data you want to encode into the input field.
3. Click the "Encode" button to start the encoding process.
4. The Base64-encoded representation of the binary data will be displayed in the output field.
5. You can copy and paste the encoded data to use it in your application or download it as a text file.

Here's an example of text to Base64 encoding:

Let's say you have the following text string: "Hello, World!"
This text string is first converted into binary data:
01001000 01100101 01101100 01101100 01101111 00101100 00101111 01110111 01101111 01110010 01101100 01100100 00100001
Next, we divide the binary data into 6-bit blocks:
010010 000110 010110 110011 000110 110111 001011 000110 011101 100111 000110 010010 100100 001000 000100
Finally, we convert each 6-bit block into an 8-bit character from the Base64 character set:
S G V x O 7 + J W E h
The resulting Base64-encoded string is: "SGVsbG8sIFdvcmxkIQ==".
