3. hex : Returns random id as 32 character hexadecimal string.

How do I get uuid?

The procedure to generate a version 4 UUID is as follows:

1. Generate 16 random bytes (=128 bits)
2. Adjust certain bits according to RFC 4122 section 4.4 as follows:
3. Encode the adjusted bytes as 32 hexadecimal digits.
4. Add four hyphen “-” characters to obtain blocks of 8, 4, 4, 4 and 12 hex digits.

How do I get 16 digit uuid?

It is not possible to generate 16 character length of UUID A HEX value is base 16. If you want to represent the same 128bit value in 16 digits then you’ll need to use base 64 digits. To do that you’ll need to create a mapping similar to how HEX values are mapped.
