<p>CryptographyRSPluginExtending-rww.7.mcz now has all 7 missing
primitives, for the FECDecoder, the GFPoly and the
GaloisCodingLoop. Here is a list.</p>

<p>A bit more detail on my refactoring. I combined the Plugins to
1 RSPlugin.<br/>
</p>
<p>I updated the package: CryptographyRSPluginExtending to include
all problematic primitives and their send sites. This includes
GFPolyWithPlugin>>#initializeField:coefficients: and the
ErasureOutputByteInputCodingLoopWithPlugin methods. To load this
extension (which blows up the image by the way) run this
compound script:</p>
<blockquote>
<p>Installer ss<br/>
project: 'Cryptography';<br/>
install: 'ProCrypto-1-1-1';<br/>
install: 'ProCryptoTests-1-1-1';<br/>
install: 'CryptographyRSPlugin'.<br/>
</p>
<p>Installer ss<br/>
project: 'Cryptography';<br/>
install: 'CryptographyRSPluginExtending'.<br/>
</p>
</blockquote>
<p>To unload and restore prior functionality, run this compound
script:</p>
<blockquote>
<p>Installer ss<br/>
project: 'Cryptography';<br/>
unload: 'CryptographyRSPluginExtending'.<br/>
<br/>
Installer ss<br/>
project: 'Cryptography';<br/>
install: 'CryptographyRSErasure';<br/>
install: 'CryptographyRSFEC';<br/>
install: 'CryptographyRSPlugin'.<br/>
</p>

<p>I consolidated the RS Plugins into 1 RSPlugin class. Here is

<p>Hi Levente,</p>
<p>I hope you are having a great day! Are you in Budapest?
That must be awesome! A very old city.</p>
<p>I thought I would post the Squeak code for this
instantiatePoly primitive. My image still blows up on
startUp:. I am grateful you have guided me through this!<br/>

I may be passing the field into the primitive instead
