Base64īase64 is designed to carry data stored in binary formats across channels that only reliably support text contentīase64 was essentially designed to trick computers… kind of. You could also call ASCII Base128 because its alphabet is made up of 128 characters.

In order to represent the NUL character, we need to store 00000000, which is a lot of wasted zeros! It is worth noting that ASCII can work with only 7 bits, but because computers work in base-2, it is more simple to use a full byte. Data Compression Rank: 3rdĮach character (typically) takes an entire byte (8 bits) of data. ASCII is based on how typewriters worked in the pre-computer days.
ASCII is meant to be used in applications that need a simple way to represent Latin-based text, the Arabic numerals, and formatting characters like newlines and spacing. Not all human language characters are possible using ASCII, but the most important ones are. Start our Back-end Career Path ASCII Encoding

For example, in Base64 the binary code 000000 represents the letter A, but in ASCII the binary 00000000 represents the NUL character. These encoding formats (Base64, Base58, and ASCII) are just different ways of reading and writing binary data. , Base64, and ASCII encoding against each other using these metrics! First: A Note on BinaryĪll data is stored in a raw binary format on computers. Efficient data compression: How many bytes are used to represent the same data, and how many characters are available?.Human Readability: Do humans have a good idea of what is being represented at a glance?.When it comes to data encoding, there is typically a trade-off made between: Also, if you came here confused, encryption and encoding are not the same! Take a look at this article for more information on encryption vs encoding
Base58 is just another encoding format (with 58 characters instead of 64, and has gained popularity largely due to Bitcoin and other cryptocurrencies. Have some binary data? Base64 encodes it for convenient readability and parsing. Base64 is one of the most popular encoding formats for representing data.
