Dec 27, 2022 · just wondering why. Because Base64 has fewer meaningful bits per byte than a binary data format (usually 6 instead of 8). This is specifically so it can survive various textual transformations that binary data would not. Wikipedia's page has a good diagram showing this:
Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
Nov 28, 2023 · So you need base64 when: Incompatible data is transmitted through the network. First of all it's a problem of emails – for example, encoding is necessary when you need to attach an image to a textual message. This was the reason why base64 was first introduced. Incompatible data is stored in files or elsewhere.
May 9, 2023 · The encoding process involves dividing the binary data into 24-bit groups (3 bytes) and then converting each group into a 4-character string. Here’s a step-by-step explanation of how Base64 ...
Aug 26, 2024 · Base64. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by transforming it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to ...
Oct 13, 2021 · We then work out the offset of each character per group, whose value in the 6-bit binary is then used to create the long 24-bit value, and then split this value into the three original bytes. If the Base64 four-character group has padding equal signs, you will need to consider fewer 6-bit groups and remove the padding zeros from the offset bits.

Dec 16, 2022 · Image: Shutterstock / Built In. Base64 is a binary to a text encoding scheme that represents binary data in an American Standard Code for Information Interchange (ASCII) string format. It’s designed to carry data stored in binary format across the channels, and it takes any form of data and transforms it into a long string of plain text.
