encryption - HSM - cryptoki - opening sessions overhead -

-

I have a question about sessions with HSM.

I know that if there is an overhead, you will start and finalize the Cryptoki API for each file, which you want to encrypt / decrypt.

My questions are,

  1. Is there an overhead in opening and closing a person session for each file, you want to encrypt / decrypt. (C_inilize / c_finelize)

  2. In addition to affecting the display, how many sessions can be the maximum number of simultaneous HSM?

  3. Is the best method for processing individual files or opening a session and opening and closing sessions for processing multiple files and then closing the best way to session ?

thanks

First of all, the normal form There are very detailed documentation from threads, applications and sessions about observation.

Secondly, this depends on your HSM Hardwa again and how does PKCS # 11 module implementation represent your PKCS # 11 provider slot? Do you use the same key all the time? What are the authentication mechanisms for the key?

  1. How to use C_Initialize (and C_Finalize) in the details of PKCS # 11 on a large scale
  2. Number of sessions PKCS # 11 implementation, see CK_TOKEN_INFO in ulMaxSessionCount < / Li>

Try with a session Are you sure your handicap will manage the session?

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>
