encryption - AES acceleration for Java -

-

I want to encrypt / decrypt many small (2-10 KB) data for now, the display is OK: Core On 2 Duo, I get around 90 Mbit / s AES 256 (when using 2 threads). But I may need to improve it in the future - or at least reduce the effect on the CPU.

  • Is it possible to use dedicated AES encryption hardware with Java (using JCE, or maybe a separate API)?
  • Does Java want to take advantage of better CPU features (SSE 5 ?!), if I get a better CPU?
  • Or are there a fast JCE provider? (I tried Suns and Bouncy Castell - there is no big difference.)
  • Other possiblilities?

    • JVM will take advantage of special CPU features while executing code to be AVS encryption: AES Identifying some code as the implementation of JIT is beyond the compiler's capabilities. To use special hardware (such as "locking" on VIA processors, or using the instructions given on the new Intel processor), you should go to some point, through the "basic code". Perhaps, a JCE provider can do this for you, I am not aware of any of the easily available JCE providers, including adapted native code for AES (a project was called, but It seems that it has been stopped and I do not know its status). Although it is predicted that SunJCE will be in the future version (but with the purchase of Oracle, with the hypersensitivity of Sun and OpenJDK 7, it is not clear when the next Java version will be released). Alternatively, cut bullets and use your native code. Local code, and is used for native AES code, is a popular implementation when you get a bigger and new processor with AES-NI instructions, replace that code with some code Know about

    By using AES-256 instead of AES-256, you should meet A + 40% speed boost, breaking AES-12, is currently beyond the technical reach of mankind, and for the next few decades it remains. needed. Do you really need 256 bit keys for AES?

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
