Random hashes

    

    

Changing tiles parameter

1	2	3	4	5	6	7	8	9	10

Rendered using the same hash.

Increasing tiles inserts more patterns inside while keeping patterns outside identical.

The default value is 6. The value from 3 to 8 is recommended.

Smaller value may tend to yield similar identicons among hashes.

Changing colors parameter

1	2	3	4	5	6	7	8	9	10

Rendered using the same hash.

Increasing colors changes the whole pattern as color values are taken from hash first.

The default value is 2. The value from 1 to 3 is recommended.

Larger value may yield identicons that look cluttered.

The parameter just specifies maximum colors to use, and more colors requires rather more entropy (see below.)

Required hash length

The required hash entropy increases as you specify more tiles/colors.

You can call Identicon->getMinimumHashLength() to know in reality how many characters are needed.

T\C	1	2	3	4	5	6	7	8
1-2	10	16	22	28	34	40	46	52
3-4	12	18	24	30	36	42	48	54
5-6	15	21	27	33	39	45	51	57
7-8	19	25	31	37	43	49	55	61

Algorithm	Hex length
MD5	32
SHA-1	40
SHA-224	56
SHA-256	64
SHA-384	96
SHA-512	128

MD5 is the best for the recommended range.
