Hashes

Following hashes are supported.

base values are used in the base category. It is the initial vector of the hash algorithm.
If the value is empty, then the base category is unsupported for the hash algorithm.

max
maximal hash value
min
minimal hash value
bmax
hash value with maximal amount of 1 bits
bmin
hash value with maximal amount of 0 bits
smax
maximal value of (sum of each byte of the hash value)
smin
minimal value of (sum of each byte of the hash value)
lsim
minimal difference between text (lowercase) and hash value
usim
minimal difference between text (uppercase) and hash value
blsim
minimal bit difference between text (lowercase) and hash value
busim
minimal bit difference between text (uppercase) and hash value
base

For *sim, the original text must be hexadecimal, and its length must be identical to that of the hash.

API

All operations are done by submitting a request on https://0xF.kr/hash/<hash>.
For example, https://0xF.kr/hash/md5 gives the current status of md5 hash values.

Two kinds of formats are supported: type=json (default) and type=text.
For example, https://0xF.kr/hash/md5?type=text gives the status in plane-text format.

Getting Status

Simply send a GET request to the URL.

Each entry has four values: text, hashed, by, and time.
Other fields are trivial; time is the timestamp (from the UNIX epoch, in milliseconds) the entry was submitted.

Submitting

Send a PUT request to the URL. method=PUT can be used instead of the request type PUT.
Set text and by fields to represent text to be submitted and the name of the submitter.

Example: https://0xF.kr/hash/md5?method=PUT&text=Hello,%20world!&by=JiminP

The returned value is the list (or comma-separated in the case of type=text) of updated categories.

Both text and by fields will be trimmed. Maximum length of text is 128, and maximum length of by is 48.
Both fields must only contain printable ASCII characters (code 32 to 126).

Please do not send requests too rapidly. Consider sending a request every 10 second or so.
Also, while putting your name or message on text is OK, please do not put any inappropriate phrases in any of the fields.
