Most people do not understand the knowledge of this article "how to use the base64 command of Linux", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to use the base64 command of Linux" article.

Linux common commands base64 commands are used to encode / decode files or standard input and output.

Usage: base64 [option]... [file] use Base64 to encode / decode files or standard input and output.

-d,-decode decode data-I,-ignore-garbag ignore non-alphabetic characters when decoding

-w,-wrap= characters wrap automatically after the specified number of characters (default is 76), 0 disables automatic line wrapping

-- help displays this help and exits-- version displays version information and exits. If no file is specified, or if the file is "-", it is read from standard input.

The data is encoded in the Base64 letter format specified by RFC 3548. When decoding, the input data (encrypted stream) may contain some new line characters that are not valid Base64 characters. You can try to recover any non-base64 characters in the encrypted stream with the-ignore-garbage option.

Example 1

[root@localhost ~] # echo test | base64 # encryption dGVzdAo= [root@localhost ~] # echo dGVzdAo= | base64-d # decryption test example 2
