QUESTION
Hi I thought this would be pretty straightforwards but I can't figure it out.
It can't find binance.websockets for whatever reason even though it can find binance.client which should be part of the same package?

QUESTION
So as a personal project of mine, I wanted to track all the WSB stonks. Unfortunately the api im using from alpha advantage has you making multiple requests for different symbols(Please correct me if I'm wrong). I was wondering if I can just use one state and map through them in one component, instead of having multiple states for each individual symbols and passing them through the same component multiple times. As you can see from my code below I'm trying to set my gmedata, amcdata, tesladata, and pltrdata to one variable called allstockdata then setStock(allstockData) but its a fail =(

I Have a PKCS#8 Key and I desperately try to import in CryptoAPI without any success. I have :
...ANSWER
Answered 2020-Oct-25 at 09:29for convert PKCS #8 format to legacy or CNG crypto api need several steps.
first need convert string to binary via CryptStringToBinaryA
with CRYPT_STRING_BASE64HEADER
than call CryptDecodeObjectEx
with PKCS_PRIVATE_KEY_INFO
(if private key encrypted need use PKCS_ENCRYPTED_PRIVATE_KEY_INFO
)
than need again call CryptDecodeObjectEx
with PKCS_RSA_PRIVATE_KEY
for legacy crypto api and CNG_RSA_PUBLIC_KEY_BLOB
for CNG.
now we can call BCryptImportKeyPair
or CryptImportKey
for import public key need use X509_PUBLIC_KEY_INFO
, for public key from cert - X509_CERT_TO_BE_SIGNED
(+ CNG_RSA_PUBLIC_KEY_BLOB
for CNG, for legacy can use CryptImportPublicKeyInfo
)
say code for legacy

QUESTION
I have read a number of pages now and am getting my mind around hashing passwords.
I created an MS Access Application which is connected to a MYSQL backend on a VPS. I'm using strong passwords for users, only allowing connections from Static IPS that I have allowed via Remote MYSQL and I am using an SSL connection with Cert and Key to the server.
My next step is to make sure the passwords are hashed and saved correctly but here is my dilemma:
- User accounts are created on my site (PHP) before downloading my application and logging in using the username and password created.
I need to find a 'decently strong but not so stupid that I can't now use it' way of saving these passwords.
I am dealing with user names and addresses and potentially some confidential info.
Now my understanding (and I'm new to this hashing stuff) is that I should: - Create a random SALT for each new password - Store the salt in the table for users - Hash it using something like bCrypt or sCrypt (SALT + PASS) - Extra safety I could use HMAC with a secret key (store on a different server)
First of all - have i understood that correctly?
Second: - bCrpyt nor sCrypt are available on VBA on ms Access and since I have users login via this method I'm at a loss on where to go with this. - I did find a software package to buy (cryptoApi or something) that apparently cn give access to these in VBA adn php...
Any ideas or advice from here? Both php and vba will obviously need to use teh same systems. My current SHA1 isn't good enough by any standards!
...ANSWER
Answered 2020-May-21 at 08:03Some notes:
- HMAC is for message authentication, not hashing passwords.
- BCrypt or SCrypt are not implemented in the Windows API, while SHA256/384/512 are. SHA512 is plenty secure for hashing passwords.
If we go for SHA512, you can use a hashing approach I previously shared here. This code uses the Windows CNG API, and allowed hashing algorithms are listed here with corresponding OS support. A call is as simple as HashString("SomePassword" & "SomeSalt")
. It returns a byte array, for convenience you could convert that to Base64 but storing it as binary is more efficient.
You can use the same API for generating random numbers (salts). I've outlined an approach here focused on integers, but you might want to generate random bytes and then prepend the string to those bytes.
An additional challenge is character encoding. PHP is UTF-8, Access is UTF-16 and doesn't really do UTF-8. If you limit possible characters to ASCII, you can use StrConv
in VBA to cast the string to ANSI, and validate that there are no non-ASCII characters in there. If you want to convert strings to UTF-8 in VBA, that's another API call (WideCharToMultiByte
) you need to use before hashing. Note that unicode in password is a UX hazard, because some operating systems express special characters as composite characters, and some don't, and that difference will cause passwords to mismatch, so there's an argument to be made for keeping it ASCII.
See the hashing code down below:
QUESTION
I tried to get EC private key from cert which in certificate store by CNG API. First, I call CertGetCertificateContextProperty()
to get private key handle with CERT_KEY_CONTEXT_PROP_ID
property, but it always return false. I'm sure that the cert has private key.
Code:
...ANSWER
Answered 2020-Apr-08 at 07:15Certificates are signed public keys, they don't contain the private key. Most of the confusion stems from casual mis-use and conflation of terminology and concepts by people who don't understand cryptography properly.
For example, .cert
.cer
.crt
can contain keys and/or certificates. However, strictly a certificate
is a signed public key.

i've been struggling with this, would appreciate help.
i'm looking to update the value of "v.low" to like 6000 (manually) outside of the loop at the last index position in the array (last index = latest timestamp, so its current time). But i can't target the entry properly in the array with JS.
here is an example - but the below is sitting in a loop where "v" is associated to the row in array

I connect to the corporate network through Cisco, and then through domain NTLM authorization to the corporate https site.

QUESTION
I tried to sign and verify by C++ cryptoAPI and it works well. The cryptoAPI use the certificate from the store(Personal) on windows to do this. Could I do the same thing by python without export private key or input passphrase?
I tried pycrypto, oscrypto, wincertstore module, but they can't do this.
...ANSWER
Answered 2020-Jan-22 at 07:15You can interface with the Crypt32
dll
Using ctypes to access it's functions.
How can I use a DLL file from Python? provides a good idea, but is written in python 2.5, so see the tutorial in the docs for info and a reference.
