Online SHA256 Hash Generator

I've tried to change multer/storage/disk.js file so I can storage a hash everytime I upload a file, but the fact is that I'm always getting the same hash even uploading different files.

This is what I've done.

DiskStorage.prototype._handleFile = function _handleFile (req, file, cb) {  var that = this  var hash = crypto.createHash('sha256')  that.getDestination(req, file, function (err, destination) {    if (err) return cb(err)    that.getFilename(req, file, function (err, filename) {      if (err) return cb(err)      var finalPath = path.join(destination, filename)      var outStream = fs.createWriteStream(finalPath)      file.stream.pipe(outStream)      outStream.on('error', cb)      outStream.on('data', function (chunk) {        hash.update(chunk)      })      outStream.on('finish', function () {        cb(null, {          destination: destination,          filename: filename,          path: finalPath,          size: outStream.bytesWritten,          hash: hash.digest('hex')        })      })    })  })}

It' s like this section isn't doing anything

outStream.on('data', function (chunk) {        hash.update(chunk)      })

I am upgrading Artifactory Pro from 4.12.2 to 6.5.2. On my test instance, with around 12k artifacts, the re-indexing of the database after the upgrade takes around 12 hours. I'm afraid in my prod instance it will take close to a month (around 800k artifacts). - Has anyone seen this before? I did not find any articles that would indicate such a long time- Is there a way to tune parameters to speed up the indexing?- Is there a way to predict how much time my prod indexing would take? If it is based on number/size/type of artifacts?

Specifications:Artifactory in HA mode installed on linux server. DB MSSQL 2016. Filestore - NAS shared mount between the HA nodes. Upgrading from 4.12.2 to 6.5.2.

I am using the jose-jwt library and want to create a signed JWT in C# using the RS256 algorithm for encryption. I have no experience with cryptography, so please excuse my ignorance. I see the following example in the docs:

var payload = new Dictionary<string, object>(){    { "sub", "mr.x@contoso.com" },    { "exp", 1300819380 }};var privateKey=new X509Certificate2("my-key.p12", "password", X509KeyStorageFlags.Exportable | X509KeyStorageFlags.MachineKeySet).PrivateKey as RSACryptoServiceProvider;string token=Jose.JWT.Encode(payload, privateKey, JwsAlgorithm.RS256);

which shows the use of a p12 file, but how do I use an RSA key file of the form below? I am looking at the docs for X509Certificate2, but I see no option for RSA private keys. It appears to only accept PKCS7, which I understand to be public keys.

Finally, what is the difference between the two options listed in the docs, and how do I choose between the two?

-------------------------- OPTION 1 --------------------------

RS-* and PS-* family

CLR:

RS256, RS384, RS512 and PS256, PS384, PS512 signatures require RSACryptoServiceProvider (usually private) key of corresponding length. CSP need to be forced to use Microsoft Enhanced RSA and AES Cryptographic Provider. Which usually can be done be re-importing RSAParameters. See http://clrsecurity.codeplex.com/discussions/243156 for details.

-------------------------- OPTION 2 --------------------------

CORECLR: RS256, RS384, RS512 signatures require RSA (usually private) key of corresponding length.

I have a question about JWT.
I try to create own signature and use hard-code secret key "hello1234567890987654321test1234".
And I use my function to create a signature and post to https://jwt.io/ to decode.
Then this webside show me "Invalid Signature".
What's wrong about me HMACSHA256 function?
And I found the "-","_" in webside and convert "+","/" in my output signature.
How to fix my output signature?
Is this signature is correct?

I also find two HMACSHA256 methods searching in Google. I don't know which is better one.
please give me some advice about choosing this.
Thanks.

Method1:

enum CryptoAlgorithm {    case MD5, SHA1, SHA224, SHA256, SHA384, SHA512    var HMACAlgorithm: CCHmacAlgorithm {        var result: Int = 0        switch self {        case .MD5:      result = kCCHmacAlgMD5        case .SHA1:     result = kCCHmacAlgSHA1        case .SHA224:   result = kCCHmacAlgSHA224        case .SHA256:   result = kCCHmacAlgSHA256        case .SHA384:   result = kCCHmacAlgSHA384        case .SHA512:   result = kCCHmacAlgSHA512        }        return CCHmacAlgorithm(result)    }    var digestLength: Int {        var result: Int32 = 0        switch self {        case .MD5:      result = CC_MD5_DIGEST_LENGTH        case .SHA1:     result = CC_SHA1_DIGEST_LENGTH        case .SHA224:   result = CC_SHA224_DIGEST_LENGTH        case .SHA256:   result = CC_SHA256_DIGEST_LENGTH        case .SHA384:   result = CC_SHA384_DIGEST_LENGTH        case .SHA512:   result = CC_SHA512_DIGEST_LENGTH        }        return Int(result)    }}extension String {    func hmac1(algorithm: CryptoAlgorithm, key: String) -> String {        var result: [CUnsignedChar]        if let ckey = key.cString(using: String.Encoding.utf8), let cdata = self.cString(using: String.Encoding.utf8) {            result = Array(repeating: 0, count: Int(algorithm.digestLength))            CCHmac(algorithm.HMACAlgorithm, ckey, ckey.count-1, cdata, cdata.count-1, &result)        } else {            fatalError("Nil returned when processing input strings as UTF8")        }        return Data(bytes: result, count: result.count).base64EncodedString()    }}

Method2:

enum HMACAlgorithm {    case MD5, SHA1, SHA224, SHA256, SHA384, SHA512    func toCCHmacAlgorithm() -> CCHmacAlgorithm {        var result: Int = 0        switch self {        case .MD5:            result = kCCHmacAlgMD5        case .SHA1:            result = kCCHmacAlgSHA1        case .SHA224:            result = kCCHmacAlgSHA224        case .SHA256:            result = kCCHmacAlgSHA256        case .SHA384:            result = kCCHmacAlgSHA384        case .SHA512:            result = kCCHmacAlgSHA512        }        return CCHmacAlgorithm(result)    }    func digestLength() -> Int {        var result: CInt = 0        switch self {        case .MD5:            result = CC_MD5_DIGEST_LENGTH        case .SHA1:            result = CC_SHA1_DIGEST_LENGTH        case .SHA224:            result = CC_SHA224_DIGEST_LENGTH        case .SHA256:            result = CC_SHA256_DIGEST_LENGTH        case .SHA384:            result = CC_SHA384_DIGEST_LENGTH        case .SHA512:            result = CC_SHA512_DIGEST_LENGTH        }        return Int(result)    }}extension String {    func hmac2(algorithm: HMACAlgorithm, key: String) -> String {        let cKey = key.cString(using: String.Encoding.utf8)        let cData = self.cString(using: String.Encoding.utf8)        var result = [CUnsignedChar](repeating: 0, count: Int(algorithm.digestLength()))        CCHmac(algorithm.toCCHmacAlgorithm(), cKey!, strlen(cKey!), cData!, strlen(cData!), &result)        let hmacData:NSData = NSData(bytes: result, length: (Int(algorithm.digestLength())))        let hmacBase64 = hmacData.base64EncodedString(options: .lineLength76Characters)        return String(hmacBase64)    }}

Usage:

class ViewController: UIViewController {    override func viewDidLoad() {        super.viewDidLoad()        let headerString: String = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9"        let payloadString: String = "eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ"        let totalString: String = headerString + "." + payloadString        let signature1 = totalString.hmac1(algorithm: .SHA256, key: "hello1234567890987654321test1234")        let signature2 = totalString.hmac2(algorithm: .SHA256, key: "hello1234567890987654321test1234")        print("signature1 : \(signature1)") // signature1 : L9YSDasvO2B5i8FZUczC+MAtSsTuM0Dj+FEpfn6uoRs=        print("signature2 : \(signature2)") // signature2 : L9YSDasvO2B5i8FZUczC+MAtSsTuM0Dj+FEpfn6uoRs=    }}

How would I SHA256 encrypt each line in a csv file in Windows?

It's a simple csv file of email addresses and I want that converted to SHA256 hashes, not the clear text emails.

macOS/Linux is my home OS, so I'm a little lost to know if this is possible on Windows?
