Signing Windows application on Linux-based distros

六眼飞鱼酱① 提交于 2019-11-27 10:57:52
I have prepared an application and website where the customer can set several options for this application before he downloads it. Settings are stored in binary format on the end of the file (appended), then the edited file is sent to the end user. The problem is that the change of "contents" of the file will break the file signature - is there any chance to re-sign this changed file with any command line tools? I've tried to use Microsoft's SignTool, but it does not work properly on Linux. It's actually quite straight forward to do using Mono 's signtool; the tricky part (described in more

Multiple OpenSSL RSA signing methods produce different results

泄露秘密 提交于 2019-11-27 09:22:56
Trying to wrap my head around signing and use/test various options. I can sign using this command: openssl dgst -sha256 -sign private_key.pem -binary -out sig_file data_file But the documentation seems to say that I can also use this method openssl dgst -sha256 -binary data_file > hash_file openssl rsautl -sign -inkey private_key.pem -keyform PEM -in hash_file > sig_file2 But the signatures are different when I'd expect them to be identical. Either I missed something in the options or something else is wrong in my assumptions. The real question from this issue: Is there a way to sign using

问题 I am using iText 5.5.5 for Java and I would like to create signed PDF with external signature as follows: Take the PDF document that should be signed and create PDF with empty signature and provide BASE64 encoded bytes to be signed by external signature mechanism: PdfReader reader = new PdfReader(src); FileOutputStream os = new FileOutputStream(dest); PdfStamper stamper = PdfStamper.createSignature(reader, os, '\0'); PdfSignatureAppearance appearance = stamper.getSignatureAppearance();

Are RSA signatures unique?

こ雲淡風輕ζ 提交于 2019-11-27 07:13:35
问题 I want to know if RSA signatures are unique for a data. Suppose I have a "hello" string. The method of computing the RSA signature is firstly to get the sha1 digest(these are , I know, unqiue for data), then add a header with OID and padding scheme mentioned and do some mathematical jiggle to give the signature. Now assuming padding is same, will the signature generating by openSSL or Bouncy Castle be same? If yes, my only fear is, won't it be easy to get back the "text"/data?? I actaully

Wonder if there are any nontrivial ways of finding number's sign ( signum function )? May be shorter / faster / more elegant solutions than the obvious one var sign = number > 0 ? 1 : number < 0 ? -1 : 0; Short excerpt Use this and you'll be safe and fast function sign(x) { return typeof x === 'number' ? x ? x < 0 ? -1 : 1 : x === x ? 0 : NaN : NaN; } Results For now we have these solutions: 1. Obvious and fast function sign(x) { return x > 0 ? 1 : x < 0 ? -1 : 0; } 1.1. Modification from kbec - one type cast less, more performant, shorter [fastest] function sign(x) { return x ? x < 0 ? -1 : 1

Negative numbers are stored as 2's complement in memory, how does the CPU know if it's negative or positive?

大城市里の小女人 提交于 2019-11-27 05:33:28
问题 -1 can be represented in 4 bit binary as (2's complement) 1111 15 is also represented as 1111. So, how does CPU differentiate between 15 and -1 when it gets values from memory? 回答1: The CPU doesn't care whether a byte holds -1 or 15 when it moves it from one place to another. There's no such thing as a "signed move" (to a location of the same size - there is a signed move for larger or smaller destinations). The CPU only cares about the representation when it does arithmetic on the byte. The
