How do you convert hexadecimal to base64?

edit

To convert hexadecimal to base64, follow these steps:

1. Convert the hexadecimal to binary.
2. Group the binary digits into groups of 6.
3. Convert each group of 6 binary digits into the corresponding base64 character.
4. Add padding characters if necessary.

Example:

1. Convert the hexadecimal value "1A3" to binary:

   • "1" = 0001
   • "A" = 1010
   • "3" = 0011
   • Combined binary value = 0001101010011

2. Group the binary digits into groups of 6:

   • 000110 101001 1

3. Convert each group of 6 binary digits into the corresponding base64 character:

   • 000110 = "G"
   • 101001 = "p"
   • 1 = "="
   • Final base64 value = "Gp="

4. Add padding characters if necessary. Since the binary value was not evenly divisible by 6, we added one "=" padding character at the end of the base64 value.

Therefore, the hexadecimal value "1A3" is equal to the base64 value "Gp=".
