Conversion from Hex to Base64
Converting a hexadecimal (hex) number to base64 involves changing the base of the number system while maintaining its value. In hex, each digit represents 4 bits of the binary system, while in base64, each digit represents 6 bits. This conversion allows for more efficient storage and transmission of data, especially when dealing with binary information.
For example, if you have a hex number "1A3F", you can convert it to base64 by first converting the hex number to binary (00011010 00111111) and then grouping the binary digits into groups of 6 (000110 100011 110). Each 6-bit group corresponds to a base64 character, so the final base64 representation would be "G9f".
Common use cases for converting hex to base64 include encoding data for transmission over protocols such as HTTP headers, encoding binary data for safe transport in email messages, or encoding cryptographic keys for secure storage. Base64 encoding is also commonly used in data encoding schemes such as MIME.
