Serializations
Serialization is how the value should be stringified for signing and for transfer between systems. Most serializations use outside standards, but some requiring additional clarifications are provided here.
decimal
Used to represent integers. Strings are used to avoid issues with different implementations of numbers.
- MUST use 0-9 representation
- MUST NOT have spaces or separators
- MUST be a string
| Invalid | Why | Valid |
|---|---|---|
"0x123" | Must be decimal | "291" |
291 | Must be a string | "291" |
"291n" | BigInt(291) serialization appends an n | "291" |
base32 multibase
Used to represent bytes.
A base32 multibase string is self-identifying and always begins with the b character.
The Multibase Table describes this encoding as “RFC4648 case-insensitive - no padding”.
- MUST use RFC4648 §6 alphabet
abcdefghijklmnopqrstuvwxyz234567 - MUST be lowercase
- MUST be prefixed with
b - MUST NOT have spaces or separators
- MUST NOT end with or contain padding characters (
=)
| Invalid | Why | Valid |
|---|---|---|
BDYQDUA4T | Must user lowercase | bdyqdua4t |
dyqdua4t | Missing b prefix | bdyqdua4t |
b3og3k0sj | Wrong alphabet (base32hex was used) | bdyqdua4t |
bdyqdua4t= | Must not have padding characters | bdyqdua4t |
