Undeclared 'nanos' in Cryptology extension to DateAndTime

Hi Tim,

I am confused. I have no failing tests and no entry of #nanos into Undeclared. It relies on the following method implementation, no reference to #nanos:

nanoSecond

    ^utcMicroseconds \\ 1000000 * 1000

This is called by

milliseconds

    ^ self nanoSecond // 1000000.

Did you load Cryptography other than

Installer ss project: 'Cryptography'; install: 'ProCrypto-1-1-1'.

Let me know where the issue is and I will get on it. Perhaps I don't know how to check Undeclared. I 'explore it' to Undeclared and get a WeakIdentityDictionary.

Whilst checking things after installing Seaside and Cryptography I noticed that Undeclared included 'nanos'.

This is only referenced in DateAndTime>>#milliSecond, which actually breaks the four Cryptology tests that fail because the result is nil and sending #asTruncateString: to nil doesn't do anything very useful. I suspect that a decent implementation would be

milliSecond

	^utcMicroseconds \\ 1000000 // 1000

It certainly stops the four tests failing.

Strange OpCodes: RDR: Rotate Disk Right

Hi tim,

Ah, well after failing to spot anything advising differently I loaded with

Installer ss project: 'Cryptography';  install:  'Cryptography'

in the belief this would get the current versions.

Having now tried

Installer ss project: 'Cryptography'; install: 'ProCrypto-1-1-1'.

in a clean image I can confirm that it does not result in any Undeclared, which is good.

However, it failed to load the BlowfishTests class that was in the original Blowfish package per Paul DeBruiker, which would be helpful to have included. I used them a couple of days ago to help work out why the string encrypt/decrypt code was so very, very, broken. I have fixes, once we are able to see the proper path to loading everything.

I am glad to see that code recovered. Sorry I missed it!

After building an image with

Installer ss project: 'Cryptography'; install: 'ProCrypto-1-1-1'.

used to load crypto, I integrated my suggested changes to Blowfish and published the change to the inbox. I hope they make things better.

Um, I have no idea how publishing to the Inbox works. At all. Please copy your version CryptographyCiphers-tpr.21 to 'Cryptography' and update ProCrypto-1-1-1 to reference it for composite loading. I added you as a User to Cryptography project, tim. Welcome aboard!

Could you explain how we may use the Inbox, please?

Kindly, rabbit

Hi K,r

I copied it from squeaksource over to smalltalkhub evidently on July 14
2013. When (and because) squeaksource was allegedly shutting down.

Can you help me understand which part of copying MIT licensed code from one
computer to another is larcency?

I really was thinking more along the lines of those other two links you mentioned below. They were not original authors, to my knowledge.

OK; after a minor panic due to forgetting my SqS password, I've updated the  CryptographyCiphers package.
I appear to have updated the mcm correctly so that it is now ProCrypto-1-1-1-tpr.14.mcm and since this is actually the first time I ever used that tool I'll be interested to know if I did it correctly.

I shall now attempt to restore the tests in some fashion, which seems to require loading the separate tests package. More later.

Installer ss
    project: 'Cryptography'; install: 'ProCrypto-1-1-1';
    project: 'Cryptography'; install: 'ProCryptoTests-1-1-1';
    project: 'Cryptography'; install: 'SSLLoader'.

Your code loaded fine. Whoops, a reproducible error! Blowfish class>>#decryptToString:with: throws MessageNotUnderstood: ByteString>>trimRight:

I just discovered .mcm files recently, myself, when I split the Cryptography monolith into these fragments: Load what you need. They are excellent and straightforwards, a difference from Metacello, IMHO. I strongly dislike the #baseline: and #configurationOf methods required in Metacello.

I really like MCMs! Montcello Configuration files link Repositories and Packages, with specific versions. Evidently, to my understanding,

***there is a way to set like a wildcard to always load the latest package *specified* [Specified is the wrong word, I meant *available*], though I have not learned how to use that.

I shall now attempt to restore the tests in some fashion, which seems to require loading the separate tests package. More later.

My apologies for failing to mention the parallel Tests packages. Please load those and the ParrotTalk/SSL stack, too.

Tim, I love reading your by-lines, I have one posted on my Facebook bio, tho I added a little squeak to it!

In /dev/null no one can hear you scream^,^

Devolution is possible, another tool to explore the fitness landscape. Some call it extinction, a healthy process, so bring it ON climate change! I really don't give a shit!

This brings to mind that The Second Law of Thermodynamics can go in reverse and be violated. In a closed system! Life creates boundaries and reverses entropy and reproduces.

Rock that glows, rocks have some level of life <heh - the waters above, over the waters below, separated by the firmament (chemical bonds between atomic structures and molecular structures)>. Consider fluorescence. Its a high/low system within a phase space, short wavelengths in and longer wavelengths out, long-time decay from a delaying energy level, a short drop from the excitation photon. Same function as a laser, a delayed energy level. So high-lambda excitation photons, excite up to A, A emits very long-lambda to immediately decay to B, a delaying energy level. Fluorescence Atom/Molecule (with a hybrid energy structure) stays at B until stochastic decay. The Rock is glowing, even at night!!! All hail the Rock!

PS. I appreciate the rare chance, and your patience, to wax lyrical about physics; and about science in the Bible!!! That really gets me going! It has been a bit on the physics.
