Group: io.crums - All Dependencies

io.crums:merkle-tree · A flexible Merkle tree implementation with support for navigating the tree's nodes and constructing Merkle proofs (about an item's existence in the set).

io.crums:io-util · I/O and other utilites. This library's more common constructs are gathered here.

io.crums:io-xp · Adds more niche capabilities to io-util. (Less commonly used constructs gathered here.)

io.crums:jsonimple · JSON library. A source-compatible, minimally updated fork of simplejson. Changes have been kept to a bare minimum so that diffs with the original are meaningful. Support for JSON indent, insertion-ordered writing, and some very lightweight object modeling goodies.

io.crums:table-io · A low level library for fixed width tables. Provides methods to sort tables using custom row-order functions, both in memory, and for larger tables, via on disk multi-merge sort. Optional keystone structures may be used to guarantee consistent table state on abnormal shutdown.

io.crums:util · A small collection of utility modules for Java Collections, JSON, general I/O (java.nio), buffers, and persistent fixed width tables.

io.crums::crums-core · Crums data model (for vending witness records), parsers (JSON) and utilities

io.crums:ledgers · Collection of modules and tools for maintaining tamper proof, evolving, historical private ledgers and for differentially revealing (reporting) any of their parts in an efficient, provable way.

io.crums:mrsl · Command line tool for working with morsel files. Verification, output, merges, redactions, as well as some minimal presentation capabilites.

io.crums:reports · An lightweight JSON template format for generating PDF reports. The goal is to embed customizable, branded templates in morsel files, so that one can output PDF reports from them.

io.crums:skipledger · The skip ledger, the base data structure as a commitment scheme for append-only ledgers. Differentially proves any cell value in the ledger using compact packaged proofs called morsels.

io.crums:skipledger-sql · SQL implementation of the hash ledger. The hash ledger is a skip ledger annotatated with crumtrails (witness records). It contains only opaque hashes. This module maintains the hash ledger on a relational database. It also models the source ledger (the data being tracked) as 2 SQL queries: one, to determine the number rows in the ledger; the second, to return the ledger row for a given row number.

io.crums:sldg · Command line tool for maintaining ledgers and emitting ledger morsels from a relational database.

io.crums:base64-32 · Command line tool for converting base64-32 encoded bytes to hexadecimal and vice versa.

io.crums:report-template · CLI for making report templates. Starting out as a hodge podge of helper commands.

io.crums::unit-io · Support of repeatable tests that need to interact with the file system. Artifact intended for scope *test*.
