![]() ![]() To ensure no extra, hidden characters are added use the -n flag. To base64 encode string you can pipe an echo command into the base64 command-line tool. While it may obfuscate that actual data from should surfers, anyone who has access to base64 encoded data can easily decode it. Rather it is a useful way of transferring or storing large data in the form of a string. Base64 is not EncryptionĮncoding files is not encryption and should never be used to secure sensitive data on disk. In short, base64 encoding ensures the integrity of our data when transferred over the network. ![]() The reason is ASCII files are string converted to bytes, and when those bytes are decoded incorrectly back to ASCII your data becomes corrupt.īase64 was introduced as a way to convert your ASCII data into arbitrary bytes, where they could then be transferred as bytes, and decoded correctly back to ASCII. Transferring an ASCII file over the network can cause corruption if not decoded correctly. OSX also comes bundled with its own version of base64. You should not have to perform any additional steps. If you are running popular linux distributions, such as Ubuntu, Debian, CentOS, or Red Hat, the base64 command-line tool is typically pre-installed. How to base64 encode on Ubuntu, Debian, OSX, and Red Hat One being is ensuring data integrity when transferring data over the network, while another is storing Secrets in Kubernetes.Īfter reading this tutorial you will understand how to easily encode files or strings, and then decode them back. You will also learn what base64 encoding is and why it should never be used to protect data from unauthorized access.īase64 encoding and decoding data has many use cases. The encrypted data is a good candidate to Base64-encode though, if you need to store the encrypted data in a text file.In this tutorial, you will learn how to base64 encode and decode from the command-line on Linux. If you need to hide your data, use encryption. Numerous tools are available to decode the data without the need for any key. If you would like to obfuscate the data, then Base64 will offer you a very poor security mechanism. ![]() Also, mail and file systems can now cope with 4 byte words containing millions of characters. Base64 encoded data might save you some trouble there. Some of those settings may contain characters that aren't allowed in the file, like encrypted passwords, html snippets or other arbitrary data. Say for example that you have an xml, unix config or java property file with settings for an application. Well, it's often used when you already have binary data and you still want to store the data in a 7 bit environment. If the last group contains two characters the encoding will have just one = character. If the last 24 bits contain only one character, that character is encoded into two characters and the last two spots will be padded with the characters =. The = character is a padding character added at the end of the encoding in case the input data is not dividable by 3. 6 bits can contain 2^6 combinations, which is 64, thus the name Base64. Each section of 6 bits is then translated into a new character in the range a-zA-Z0-9+/. Now, the resulting 24 bits are split into four sections of 6 bits instead. Since 8 bit characters consist of, well, 8 bits, Base64 encoding groups the characters into groups of three 8 bit characters, yielding 24 bits. The original RFC for Base64 was the Privacy-enhanced Electronic Mail (PEM) RFC 989 but now numerous variations exists, as well as RFC:s, like the RFC 1421, RFC 2045, RFC 3548, RFC 4848 and several other as well. This was mostly used in transfering of data across 6 or 7 bit connections. In short, Base64-encoding is a way to encode 8 bit character data in a series of 6 bit characters. ![]()
