This is done via the mime implementation of base64. For example the text. Also check our base64 encoder tool.
In case of textual data the encoding scheme does not contain their character set so you have to specify which one was used during the encoding process. Let str hello people. To base64 encode string you can pipe an echo command into the base64 command line tool.
This is to ensure that the data remains intact without modification during transport. Would be encoded as. Base64 is used commonly in a number of applications including email via mime and storing complex data in xml or json.
Which will output the following. Base64 encode your data in a hassle free way or decode it into human readable format. If you are not sure then play with the available options including the auto detect one.
Base64 encoding a file. Without the n flag you may capture a hidden characters like line returns or spaces which will corrupt your base64 encoding. Encode a text using base64.
