objecthash-java

objecthash-java is a Java version of Ben Laurie's objecthash.

This will be used by openregister-java to provide a verifiable log of data. For more details see the following RFCs:

• RFC 9: Entry hash
• RFC 10: Item hash

The set of types supported this objecthash implementation are:

• Integer
• Unicode string
• List
• Set
• Hash
• Timestamp

Timestamp is an extension. It represents a datetime in UTC with seconds precision, and is encoded by taking the ISO8601 string representation and prefixing with the tag "t".

objecthash-java does not implement Boolean or Float types.

TODO

Hash a single value:

ObjectHash.stringToHexDigest("Hello world"); // bd75f78d2f7aa16b72d9fcdb822754a10310ef4cd5b6cca6aa48d98331e246ab
