How do you do base64 encoding in Linux?

The following command will encode the data, 'linuxhint.com' and print the encoded data as output.

1. $ echo 'linuxhint.com' | base64.
2. $ echo 'bGludXhoaW50LmNvbQo=' | base64 --decode.
3. Sample. ...
4. $ base64 sample.txt.

6. $ base64 -d encodedData.txt.

How do I decode base64?

How to decode Base64 online using this decoder tool

1. Paste your string in the “Base64” field.
2. Select the algorithm standard (if you do not know, leave it as it is, as the decoder will automatically detect it).
3. Enable the strict decoding mode if you want to make sure that your Base64 string contains only valid characters.

What is base64 in Linux?

The base64 command encodes binary strings into text representations using the base64 encoding format. Base64 encoding is often used in LDIF files to represent non-ASCII character strings. It is also frequently used to encode certificate contents or the output of message digests such as MD5 or SHA.

Why is base64 needed?

From wiki: “Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport”.

How do I use tr in Linux?

tr stands for translate.

1. Syntax. The syntax of tr command is: $ tr [OPTION] SET1 [SET2]
2. Translation. ...
3. Convert lower case to upper case. ...
4. Translate braces into parenthesis. ...
5. Translate white-space to tabs. ...
6. Squeeze repetition of characters using -s. ...
7. Delete specified characters using -d option. ...
8. Complement the sets using -c option.

How do you decode secret messages?

To decode a message, you do the process in reverse. Look at the first letter in the coded message. Find it in the bottom row of your code sheet, then find the letter it corresponds to in the top row of your code sheet and write it above the encoded letter. This can be confusing at first!

Why does Base64 end with ==?

The final '==' sequence indicates that the last group contained only one byte, and '=' indicates that it contained two bytes. Thus, this is some sort of padding. No. To pad the Base64-encoded string to a multiple of 4 characters in length, so that it can be decoded correctly.

What is Base64 number?

Base64. Base64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base 64 representation. The Base64 term originates from a specific MIME content transfer encoding.
