11/13/2023 0 Comments Linux decode base64![]() The use cases are very limited since the encryption is very weak.But the reasons why Base64 no longer is as popular as it was before is that: When you need to transmit a file that contains various characters like Unicode, or has formatting that some networks don’t accept, encoding the file with Bas64 makes it possible to transmit the file. Used for transmitting data over networks that accept information only in ASCII format. Used majorly for storing passwords/sensitive data on databases and for verifying package integrity Fundamental Differences Between the MD5 and Base64 MD5ĭata once encrypted cannot be decrypted to the original formĭata once encrypted can be decrypted to their original form We’ll go over the basic syntax and some of the use cases that you can work with when using these commands. Let’s get right into it and understand the different uses of MD5 and Base64 commands. Introducing the MD5 and Base64 Commands on Linux This isn’t going to be the most optimal choice if you want to ensure security but it would be a good idea to use it if your initial idea is to send data in plaintext. On the other hand, Base64 is a regular two-way encryption algorithm that allows both encryption and decryption of the data that’s passed to it. When a user enters the password, the password is encrypted again with MD5 and the hashes are then compared on the back-end to verify that the passwords are the same. When storing passwords on the database, the most secure way is to encrypt the passwords with a one-way encryption algorithm like MD5 so it cannot be reversed. In this tutorial, we’re going to cover some of the very basic aspects of making sure that the data that’s transferred over the internet is intact and that no one has tampered with it. Encryption encodes your data in an attempt to keep it safe from unauthorized access. A loss bigger than the money is the loss of credibility. Data breaches can cause loss of thousands, if not millions. Encryption is a subject for every person tasked with keeping their data secure. In this tutorial, we covered how to encode and decode a base64 string on Linux using the base64 utility, the openssl utility, and Python.Let’s venture into encryption today and understand the md5 and base64 commands in Linux. If you want to convert this byte string to a regular string, you can use the decode method of the byte string: print(code('utf-8')) Use the b64decode method to decode a base64 string: import base64ĭecoded = base64.b64decode(b'SGVsbG8gV29ybGQ=') ![]() The code above will return a byte string: b'SGVsbG8gV29ybGQ=' Import the base64 module and use the b64encode method to encode a string: import base64Įncoded = base64.b64encode(b'Hello World') Open a Python interactive shell by typing python or python3 in your terminal. We can also use Python encoding and decoding functionality to encode and decode base64 strings. To decode a string, you use the -d or -decode option: echo 'SGVsbG8gV29ybGQ=' | openssl base64 -d To encode a string, you can echo the string and pipe it to the openssl base64 command: echo -n 'Hello World' | openssl base64 It also includes a command-line utility that can be used for various purposes, including encoding and decoding base64 strings. OpenSSL is a robust, full-featured open-source toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. To decode a base64 string, you use the -d or -decode option: echo 'SGVsbG8gV29ybGQ=' | base64 -decode ![]() The resulting string will be an base64 encoded string as: Advertisements SGVsbG8gV29ybGQ= The -n option tells echo not to output the trailing newline. For example: echo -n 'Hello World' | base64 To encode a string, you can echo the string and pipe it to the base64 command. It is typically pre-installed on most Linux distributions. ![]() The base64 utility is a command-line utility that can encode and decode base64 strings. On the other hand, decoding is the process of converting base64 encoded data back into its original binary format. This encoding process also helps us to ensure that the data remains intact without alteration during transport. Base64 is a binary-to-text encoding scheme that is commonly used to encode binary data, especially when that data needs to be sent over media that are designed to handle text.
