That’s it, now you know how to encode and decode base64 data from command line. $ echo "MTIz" | openssl base64 -d Conclusion ![]() $ openssl base64 -d -in encoded.txt -out raw.txt These are some example commands: $ openssl base64 -in raw.txt -output encoded.txt if arg takes string: /command -arg ' (base64 -d /home/base. Openssl works with same way as base64 utility. Again, there is an encoded file, that needs to be decoded and piped as an argument for another command. We have performed the commands on Ubuntu. ![]() You can also use openssl to perform base64 encoding and decoding, but it might require to install for the operating system. In this article, we will explain how to use the base64 command to encode and decode the data in a string or a file. To decode base64-encoded data, use the -d argument: $ echo "MTIz" | base64 -d If you just want to quickly perform base64 encoding for a string and get the output, use any of these commands: $ cat raw.txt | base64 The encoded base64 value, by default, is printed on the stdout if you want to save into an file, you can use either one of following commands: $ base64 -i raw.txt -o encoded.txt $ echo -n "123" > raw.txtįor some Linux distros, you might need to specify the input file by using -i, -input : $ base64 -i raw.txt In the event that I come across a better way to go about encoding a whole bunch of files at once I will see about updating this post to refer to that.To encode base64 for an input file, issue this command: $ echo "123" > raw.txtīy default, echo command will append a newline character to the output, you might want to omit it by using -n argument. I will be looking into other things to write about when it comes to Linux commands that I should be aware of when it comes to things such as this. By default, echo command will append a newline character to the output, you might want to omit it by using -n. To encode base64 for an input file, issue this command: echo '123' > raw.txt base64 raw.txt MTIzCg. For Windows, you can use this ported version. At least I have not found a way to do so with bash commands alone anyway, there is a nodejs project that I made a while ago where I as able to get something together that did just that. base64 is a very handy command line utility which is available in Linux and MacOS. So I have not yet discovered a way to go about quickly creating a bunch of files with base64 and then convert them back again with the original files names. I got as far as becoming aware of certain other commands such as cut, but gave up after a while. However the problem then is how do I go about creating a collection of files where each file is then just the original extension. This will result in a bunch of files with the b64 extension appended on the end and the content of each being base64 encoded. $ find -type f -name '*.md' -exec bash -c 'base64. Keep your favorite Git commands, aliases, and. For example, to encode the previous example: echo Hi base64 SGkK. You can use the base64 command-line utility to encode and decode files or standard input. Now that you understand how Base64 encoding works, you can work with it at the command line. If I just want to encode rather than decode I do not need to give any option to base32 or base64, the default behavior is to encode to base32 Encode and decode Base64 at the command line. So for starters there is using the Linux echo command to just create some standard output, and then pipe that output to the base32 command. 1 - A basic base32 example with echo and piping I will of course also be touching base on a few other things when it comes to using these commands to create a collection of files such as piping, redirection, and other commands that can come into play with this. So in todays Linux post I will be checking out the base32 command as well as the base64 command for doing this sort of thing on the command line in a Linux operating system environment. There is also the base64 system that will make use of upper and lower case letters and numbers. If you want to get the encoded string into other formats, you need to: Base64 with no line breaks - Open the encoded output file in a text editor and remove. The human readable form of this would be to use the uppercase letters form A to Z and the numbers 2 to 7. If you are not familiar with base32 encoding it is a base32 number system composed of 32 digits. Speaking of options what if I have some base32 or 64 code and I want to decoded it back, for this there is the -d option that will decode base32 or 64 into its original form. I would like to write a bash script to decode a base64 string. The commands can be fed some input via the standard input when it cokes to piping in what I want to encode to base32, the result is then a base32 encoding of what I piped in when it is not used with any options. ![]() The the usr bin folder on most Linux systems there should be a linux base32 and base64 commands that can be used to do quick, simple base32 and 64 encodings and decodings in the command line.
