I've been taking a stab and removing some of our dependencies on
various plexus components.
First up, plexus-digest.
I've taken the varied code from many locations and come up with a
stand alone archiva-checksum lib/component that I hope to be able to
integrate into archiva/trunk.
So ... uhm ... consider this a call for discussion. ;-)

Some more details...
These are 4 classes present in archiva-checksum
1) org/apache/archiva/checksum/Hash.java
2) org/apache/archiva/checksum/Hasher.java
3) org/apache/archiva/checksum/Hex.java
4) org/apache/archiva/checksum/ChecksumFile.java
This is how the replacements work ...
Hash.class is an enum identifying the types of Hash functions (currently
only SHA1 and MD5), with a few details on ids that the hash techniques
expose.
This is similar in scope, but not a 100% replacement for ...
org/codehaus/plexus/digest/Sha1Digester.java
org/codehaus/plexus/digest/Md5Digester.java
org/codehaus/plexus/digest/StreamingSha1Digester.java
Hasher.class is the main hashing routines, stream based, and has a few
optimizations for performing bulk or group hashing based on a single
stream, without processing the stream multiple times (one for each hash).
Hasher.class replaces the following classes in plexus-digest
org/codehaus/plexus/digest/Digester.java
org/codehaus/plexus/digest/StreamingDigester.java
Hex.class is just a simple utility class to convert a byte array to a
Hex string.
It is a suitable replacement for plexus-digest
org/codehaus/plexus/digest/Hex.java
ChecksumFile.class is the file specific implementation, for dealing with
the .md5 and .sha1 files (parsing, validating, creating, etc..)
It is a replacement for plexus-digest
org/codehaus/plexus/digest/ChecksumFile.java
org/codehaus/plexus/digest/DigestUtils.java
And also covers the logic present in archiva-common too
org/apache/maven/archiva/common/utils/Checksums.java
