Base64 Decode & Encode
Use the form below to decode base64 to string and encode a string into base64. To decode base64 to string, just enter the code into the textarea and click on “Decode”. To encode a string into bae64, enter your string in the the textarea, and click on “Encode”.
What is Base64 Encoding?
Base64 is a method of encoding data, typically text or binary data, into a string of characters that can be easily transmitted and stored. The encoded data is composed of only 64 characters from a set which includes the uppercase and lowercase letters, numbers, and some special characters.
What is Base64 Used For?
Base64 is used for a variety of purposes, such as:
- Storing binary data in a text file or database
- Encoding binary data in an HTTP or email message
- Encrypting or signing data
- Creating a one-time pad
How Does Base64 Encoding Work?
Base64 encoding works by breaking the input data into chunks of 3 bytes and representing each chunk as 4 characters, which are chosen from the 64 characters in the base64 character set. The encoded data is typically 1/3 larger than the original data, but the encoded data is still in a format that can be easily transmitted and stored.
What Are The Limitations of Base64 Encoding?
Base64 encoding has some limitations, such as:
- The encoded data is typically 1/3 larger than the original data, which can be an issue if storage or transmission space is limited.
- Base64 encoded data is not suitable for encryption or signing, as it can easily be decoded.
- Base64 encoded data is not secure against tampering, as the encoded data can be modified without detection.
Is Base64 A Type of Encryption?
Base64 is not a type of encryption like MD5 is. It is a way of encoding data so that it can be safely transmitted or stored. The encoded data can be decoded easily, so it is not suitable for encryption or signing. It is not a secure way to protect sensitive data, and it should not be used for this purpose.
