| Size of plain text stored as UTF-8 | 31 | |
| Size of text encoded as BASE64 | 44 | |
| Size change as percents (Data flow: UTF-16 → UTF-8 → BASE64) | ||
| Data storage saved after conversion from UTF-16 to UTF8 | 50 | |
| Size increased after BASE64 encoding of UTF-8 text | 41.94 | |
| Size change after BASE64 encoding related to UTF-16 | -29.03 | |
Some facts#
- BASE64 is a data encoding algorithm, which uses 64 alphanumeric characters.
- All BASE64 characters can be displayed on the standard ASCII terminal.
- BASE64 encoding can be used to transmit binary data (in practice it means any kind of data) via text protocols e.g. when sending e-mail attachments.
- Text after encoded with the BASE64 algorithm increases it's size by 1/3. This is why, for example, emails containing the attached MP3 file occupy about 33% more than it would appear from the size of the attached file.
- ⚠ WARNING! Some protocols (e.g. the SMTP e-mail protocol) use BASE64 to send passwords. However, keep in mind that the BASE64 algorithm does not guarantee security and it has not been developed for this purpose. BASE64 data can be decoded by any person.
- Because one BASE64 character occupies 6 bits (because and the data in computers is packed into 8 bit bytes, sometimes after applying the algorithm part of the last bits remains unused. To handle this scenario, a special pad character is used: = (equal sign). It appears at the end of the result string if the length of the text after encoding is indivisible into 8 bits blocks.
- BASE64 encoding was standardized in the RFC 4648 document.
