Online Base32 Encode function

What is base32

Base32 is a number system that uses a set of 32 digits. Every number can be represented by 5 bits means (25). By using 32 character set Base32 is can be represented in a human-readable format.

In the 32-character set, there are 26 upper case letters (A-Z) and (2-7) numbers.

Base32 messages have multiple of 8 characters. So (=) equal symbol is used as the last character to make it multiple of 8.

“JJXWQ3RAIRXWK”(13) Now Add “===”(3) Final Result: JJXWQ3RAIRXWK===(16)

In this example, the Base32 has only 13 character set. This is not multiple of 8. So there = (Equal Symbol) to be added to make it multiple of 8.

How to encode Base32 Complete Procedure

In base32 the data message for encoding is first treated as Binary Number System according to a predefined coding such as ASCII or Unicode. There are 8 Bit sets in Binary Number.

Example: John Doe to Base32 Encryption

Step 1: John Doe to Binary 8 bit Conversion

01001010    01101111    01101000    01101110    00100000    01000100    01101111    01100101

Step 2: Now the sets are break into 5 bits and left digits are filled by 0 to complete the pair of 5 bits.

01001    01001    10111    10110    10000    11011    10001    00000    01000    10001    10111    10110    01010

Step 3: Now these 5 bits pairs are converted into Base32 as the below table.

Conversion Table Binary to Base32 Encode

Conversion According to Base32 Table

Binary	01001	01001	10111	10110	10000	11011	10001	00000	01000	10001	10111	10110	01010
Base32	J	J	X	W	Q	3	R	A	I	R	X	W	K

According to charge we get JJXWQ3RAIRXWK(13 characters) and Base32 must have multiple of 8 characters. To make it complete. We add === symbol three times to make it multiple of 8 characters.

Now the Base32 Encoded Result of John Doe: "JJXWQ3RAIRXWK==="
