By default, the base64 command encodes the provided data, while using the -d or -decode option enables decoding. Encode all string literals of the stringArray using base64 or rc4 and inserts a special code that used to decode it back at runtime. In the Bash shell, the base64 command-line tool is used to perform Base64 encoding and decoding. If you are using a Windows system, there is no built-in command to directly perform Base64 encoding and decoding.
#Cli base64 decode string how to
Also, the equal sign (=) is used for padding in the encoded output. Windows Command - 'certutil -encode/-decode' This section provides a tutorial example on how to use 'certutil -encode' command on a Windows system to perform Base64 encoding and decoding. These characters include uppercase letters (A-Z), lowercase letters (a-z), numeric digits (0-9), plus (+), and slash (/). Base64 encoding is designed to handle data that does not contain only printable characters.īase64 encoding converts three octets of data into four encoded characters, each within a set of 64 different possible characters. import base64 from react-native-base64 base64. The syntax for decoding a Base64 string is as follows: echo 'base64encodedstring' base64 -d. Heres what worked as of January 2019: yarn add react-native-base64. To decode a Base64 string in Linux, you must use the base64 command command. Hello World this is an example base64 text for. With the following result, you can see how the base64 command on Linux decoded our file and returned the following string. This encoding scheme converts binary data into text format to ensure safe and efficient data transfer over networks that are designed to handle text. Neither the accepted answer nor the Buffer methods worked for me. All we need to do is reference base64 followed by the -d option, then finally, the file we want to be decoded.
Understanding Base64 Encodingīefore delving into the technicalities of Base64 encoding in Bash, let’s first grasp the concept of Base64 encoding.
This article will provide an in-depth exploration of Base64 encoding and decoding in the Bash environment. Among these features, Base64 encoding and decoding are two of the most frequently used, due to their widespread usage in programming, web development, and data science. The Bash shell, which is often used as the default shell in most Linux distributions, supports various commands and features that assist in data manipulation. You can use base64 <<< string and base64 -D <<< string to encode and decode a string in the terminal, or base64 -in file and base64 -D -in.
