How to load in Python-RSA a public RSA key from a file generated with openssl? -


i generated private , public key following commands:

openssl genrsa -out private_key.pem 512 openssl rsa -in private_key.pem -pubout -out public_key.pem

i tried load them python script using python-rsa:

import os import rsa  open('private_key.pem') privatefile:     keydata = privatefile.read() privkey = rsa.privatekey.load_pkcs1(keydata,'pem')  open('public_key.pem') publicfile:     pkeydata = publicfile.read()  pubkey = rsa.publickey.load_pkcs1(pkeydata)  random_text = os.urandom(8)  #generate signature signature = rsa.sign(random_text, privkey, 'md5') print signature  #verify token try:     rsa.verify(random_text, signature, pubkey) except:     print "verification failed"

my python script fails when tries load public key:

valueerror: no pem start marker "-----begin rsa public key-----" found

python-rsa uses pem rsapublickey format , pem rsapublickey format uses header , footer lines: openssl notes

-----begin rsa public key----- -----end rsa public key-----

output public part of private key in rsapublickey format: openssl examples

 openssl rsa -in key.pem -rsapublickey_out -out pubkey.pem

c# - Operator '==' incompatible with operand types 'Guid' and 'Guid' using DynamicExpression.ParseLambda<T, bool> -

i'm using dynamic linq library , there source code , basic docu , nuget version pm> install-package dynamiclinq i'm trying construct clause involves guids i have tried string "id == @0" . parameter array object[] value ( guid xxxx ) var whereclausesb = buildlogicalkeywhereclause2(entity, logicalkey); //build string var parms = buildparamarray(entity, logicalkey); // object[] var wherelambda = ofsi.bos.core.dynamicexpression.parselambda<t, bool>(whereclausesb.tostring(),parms); //parse an exception thrown in dynamicexpression.parselambda operator '==' incompatible operand types 'guid' , 'guid' i have tried guid , string.(fail) i tried , "id = @0" (fail). string == string works, int32==int32 not guid == guid not any ideas? try using equals method instead of == operator in string: "id.equals(@0)"

matlab - How to equate a structure array to structure array -

the following code doesn't work, think it's clear want do: my.struct = 1; foo.bar = my.struct; so that foo.bar.struct = 1 basically want fill in my structure array bunch of fields , values. want place struct nested struct within foo.bar while retaining field names. my.struct = 1; foo.bar = my.struct; this places value of my.struct (= 1 ) in foo.bar . of course foo.bar 1 . i think you're after this: my.struct = 1 foo.bar = my;
