Base10

The multibase base10 prefix is the character 9.

Encoding

A byte array is encoded to multibase base10 by prefixing its base10 encoding with the character 9.

A byte array is encoded to base10 by:

  1. Counting the number of leading 0 bytes (Z).
  2. Interpreting the rest of the byte array as a big-endian unsigned integer (N).
  3. Concatenating a length Z string of '0' characters with the decimal representation of N.

Decoding

A multibase base10 encoding is decoded by first dropping the multibase prefix (which must be 9).

The remaining characters are then converted to a byte array by:

  1. Counting the number of leading '0' characters (Z).
  2. Interpreting the rest of the character sequence as a base10 unsigned integer (N).
  3. Concatenating a length Z array of NULL (0x00) bytes with N encoded as a big-endian unsigned integer.

Examples

Byte Array <-> Base10 Multibase:

  • [0x00, 0x01] <-> "901"
  • [0x00, 0x00, 0xff] <-> "900255"
  • [0x01, 0x00] <-> "9256"
  • [0x00, 0x01, 0x00] <-> "90256"
