fc3bd0c987 use added secret to protect convergent encryption
Now upload or encode methods take a required argument named "convergence" which can be either None, indicating no convergent encryption at all, or a string, which is the "added secret" to be mixed in to the content hash key.  If you want traditional convergent encryption behavior, set the added secret to be the empty string.

This patch also renames "content hash key" to "convergent encryption" in a argument names and variable names.  (A different and larger renaming is needed in order to clarify that Tahoe supports immutable files which are not encrypted content-hash-key a.k.a. convergent encryption.)

This patch also changes a few unit tests to use non-convergent encryption, because it doesn't matter for what they are testing and non-convergent encryption is slightly faster.

567979ba85 lower max_segsize for immutable files to 128KiB, to make download-progress smoother and improve alacrity. Closes #252. Note that mutable files continue to use 1MiB segments. 2008-03-07 19:24:51 -07:00

7c6de95bc6 switch from base62 to base32 for storage indices, switch from z-base-32 to rfc 3548 base-32 for everything, separate out base32 encoding from idlib 2008-02-14 19:27:47 -07:00

3f8df27063 use base62 encoding for storage indexes, on disk and in verifier caps, and in logging and diagnostic tools
base62 encoding fits more information into alphanumeric chars while avoiding the troublesome non-alphanumeric chars of base64 encoding.  In particular, this allows us to work around the ext3 "32,000 entries in a directory" limit while retaining the convenient property that the intermediate directory names are leading prefixes of the storage index file names.

da9610e90a change encryption-key hash to include encoding parameters. This is a minor compatibility break: CHK files encoded (with convergence) before and after this will have different keys and ciphertexts. Also switched to SHA-256d for both the data-to-key hash and the key-to-storageindex hash 2008-02-06 19:50:47 -07:00
