signature

问题 I'm trying to sign a mail using PGP in php. I could bring the boundaries and headers to work correctly but the mail signature isn't valid (as Thunderbirds Enigmail states). My question here is what part is to sign and what is to take attention to while doing it. At the moment the source of the generated mail looks like this (Text and signature replaced by placeholders to keep it easy to read): Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="=

问题 Python 3.6 I'm attempting to create a decorator that automatically assigns the string of the argument as the default value. such as: def example(one='one', two='two', three='three'): pass would be equivalent to: @DefaultArguments def example(one, two, three): pass Here is my attempt (doesn't work.. yet..) DefaultArguments : from inspect import Parameter, Signature, signature class DefaultArguments(object): @staticmethod def default_signature(signature): def default(param): if param.kind in

问题 I'm working with code that works in Python 2.7, but when I use it with 3.6, it doesn't work. It's meant to encode a signature for an Amazon MWS API call. The original code in Python 2.7: sig_encoded = base64.b64encode(hmac.new(str(self.secret_key), sig_data, hashlib.sha256).digest()) I read a few other posts here, followed the instructions, and came up with this: Python 3.6 key_enc = (bytes(self.secret_key, "utf-8")) sig_data_enc = (bytes(sig_data, "utf-8")) sig_encoded = base64.b64encode

问题 I have a java server that communicates with a java client via json-rpc. The client is supposed to report internal stats to the server which modifies the servers behaviour. Both client and server compenents are written in house so I can control what the client does and how it reports stats but is there a way I can verify that the client code hasn't been modified? If it has it will still service the client but using some default behaviours. The clients will be publicly available so it's not a

问题 many antivirus programs using signature-based malware detection. Here is creating signatures for ClamAV. I can understand how they create signatures considering that the whole file is a malware, but I couldn't understand how to find malware when it is in the body of the file - the hash would be another. Anybody knows? 回答1: My answer is not specific to ClamAV; instead I've answered in a general sense. Maybe this is helpful for you. First of all a virus signature is not necessarily a hash value

问题 I have a keystore and a apk. is there a tool or a method to check file apk, signed from this keystore? I use Eclipse. Someome help me please. Thanks so much 回答1: Use jarsigner tool: jarsigner -verify -verbose -keystore keystore_file apk_file.apk This command gives output like this: smk 22401 Tue Aug 30 10:20:52 SAMST 2011 res/drawable/about_cover.png smk 1206 Tue Aug 30 10:20:52 SAMST 2011 res/drawable/add_normal.png smk 1430 Tue Aug 30 10:20:52 SAMST 2011 res/drawable/app_icon.png smk 133

问题 I was playing around with a Perl 6 implementation of a command-line program that takes several switches. The signature to MAIN was quite involved and a bit messy. I wondered if there was a way to define the signature somewhere else and tell the subroutine what to use: # possibly big and messy signature my $sig; BEGIN { $sig = :( Int $n, Int $m ) }; multi MAIN ( $sig ) { put "Got $n and $m"; } MAIN doesn't see the variables in the signature even though the signature is set before MAIN compiles

问题 Is it possible to create an HTML email signature for Outlook 2003 or above that doesn't reference external images? That is, using those special "cid" reference but embed the image itself in the signature and not on the file system or network. This is for an web application that generates a "standard" email signature based on various input from a user. It has worked fine so far with a single "embedded" image. But a new feature is going to require the possible addition of multiple tiny images.

问题 I need to extract the user certificate from a pkcs7 signature file. I can do it via the command line using the following: openssl pkcs7 -in somesign.pks7 -inform PEM -print_certs This will give me the entire certificate chain and I can process the resulting file to extract what I want. Is there any way to do that with the openssl_pkcs7_ commands? I saw that openssl_pkcs7_verify has the $outfilename where the certs would be stored but I don't have the signed message, but it seems the $filename
