How Does Base64 Encoding Work?

1. Take the ASCII value of each character in the string.

3. Convert the 8-bit chunks into chunks of 6 bits by simply re-grouping the digits.
4. Convert the 6-bit binary groups to their respective decimal values.

How to encode and decode text in base64?

Create a text file named, ‘ sample.txt ’ with the following text that will be encoded by using base64. You can print the encoded text in the command line or store the encoded text into another file. The following command will encode the content of the s ample.txt file and print the encoded text in the terminal.

How to encode and decode from command line?

To base64 encode a file. base64 /path/to/file. This will output a very long, base64 encoded string. You may want to write the stdout to file instead. bas64 /path/to/file > output.txt Decoding Strings. To decode with base64 you need to use the –decode flag. With encoded string, you can pipe an echo command into base64 as you did to encode it.

How does Bash encode and decode in Linux?

Bash base64 encode and decode. To encode or decode standard input/output or any file content, Linux uses base64 encoding and decoding system. Data are encoded and decoded to make the data transmission and storing process easier. Encoding and decoding are not similar to encryption and decryption. Encoded data can be easily revealed by decoding.

What can you do with the Base64 command?

You can use different types of options with base64 command. Data can be taken from any file or standard input while encoding or decoding. After encode or decode, you can send the output in a file or print the output in the terminal. This option is used to encode any data from standard input or from any file.
