Node js https pem error routines PEM read bio no start line

Question

I am messing with login form right now with node js  I tried creating a pem key and csr using   openssl req -newkey rsa 2048 -new -nodes -keyout key pem -out csr pem   However I been getting errors for running node server js  Here is my server js  var http   require  http        express   require  express    UserServer   require    lib user-server     var https   require  https    var fs   require  fs     var options       key  fs readFileSync    key pem    utf8      cert  fs readFileSync    csr pem    utf8       var app   express     app configure function      app use express bodyParser       app use app router     app use express static   dirname     public          var httpserver   http createServer app  listen  3004    127 0 0 1    var https server   https createServer options  app  listen  3005    127 0 0 1    UserServer listen https server     Here is the error  crypto js 104   if  options cert  c context setCert options cert                               Error  error 0906D06C PEM routines PEM read bio no start line     at Object exports createCredentials  crypto js 104 31      at Server  tls js 1107 28      at new Server  https js 35 14      at Object exports createServer  https js 54 10    I tried running   openssl x509 -text -inform DER -in key pem   It gives  unable to load certificate 140735208206812 error 0D0680A8 asn1 encoding routines ASN1 CHECK TLEN wrong tag tasn dec c 1319  140735208206812 error 0D07803A asn1 encoding routines ASN1 ITEM EX D2I nested asn1 error tasn dec c 381 Type X509   I am not exactly sure what does the error mean as my encryption file is  pem file already  so any help would be much appreciated   Thanks

You are probably using the wrong certificate file, what you need to do is generate a self signed certificate which can be done as follows

openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem
openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out server.crt

then use the server.crt

   var options = {
      key: fs.readFileSync('./key.pem', 'utf8'),
      cert: fs.readFileSync('./server.crt', 'utf8')
   };

Generate the private key and server certificate with specific expiry date or with infinite XXX  expiry time and self sign it     openssl req -x509 -sha256 -newkey rsa 2048 -keyout key pem -out cert pem -days XXX   Enter a private key passphrase      Then it will work

For me  the solution was to replace   n  getting formatted into the key in a weird way  in place of  n Replace your key   lt private or public key gt  with key    lt private or public key gt   replace new RegExp  quot     n quot    quot  g quot     quot  n quot

If you log the   var options       key  fs readFileSync    key pem    utf8      cert  fs readFileSync    csr pem    utf8        You might notice there are invalid characters due to improper encoding

I actually just had this same error message   The problem was I had key and cert files swapped in the configuration object

I removed this error by write the following code   Open Terminal   openssl req -newkey rsa 2048 -new -nodes -keyout key pem -out csr pem openssl x509 -req -days 365 -in csr pem -signkey key pem -out server crt   Now use the server crt and key pem file  app js or server js file   var https   require  https    var https options       key  fs readFileSync  key pem    utf8      cert  fs readFileSync  server crt    utf8       var server   https createServer https options  app  listen PORT   console log  HTTPS Server listening on  s  s   HOST  PORT     It works but the certificate is not trusted  You can view the image in image file

I guess this is because your nodejs cert has expired  Type this line   npm set registry http   registry npmjs org  and after that try again with npm install   This actually solved my problem

Corrupted cert and or key files   For me it was just corrupted files  I copied the contents from GitHub PullRequest webpage and I guess I added an extra space somewhere or whatever    once I grabbed the raw thing and replaced the file  it worked

If you are using windows  you should make sure that the certificate file csr pem and key pem don t have unix-style line endings  Openssl will generate the key files with unix style line endings  You can convert these files to dos format using a utility like unix2dos or a text editor like notepad

For me  after trying all above solutions it ended up being a problem related to encoding  Concisely  my key was encoded using  UTF-8 with BOM   It should be UTF-8 instead   To fix it  at least using VS Code follow this steps    Open the file and click on the encoding button at the status bar  at the bottom  and select  Save with encoding   Select UTF-8   Then try using the certificate again    I suppose you can use other editors that support saving with the proper encoding   Source  error 0906d06c pem routines pem read bio no start line  when importing godaddy SSL certificate   P D I did not need to set the encoding to utf-8 option when loading the file using the fs readFileSync function   Hope this helps somebody

Was facing the same problem In my case I changed the option parameter of cert to pfx  amp  removed utf8 encoding   before   var options         hostname    localhost       path            method    POST       cert  fs readFileSync testCert   utf8        passphrase passphrase      agent false      rejectUnauthorized false      after   var options         hostname    localhost       path            method    POST       pfx  fs readFileSync testCert       passphrase passphrase      agent false      rejectUnauthorized false

I faced with the problem like this   The problem was that I added the public key without  -----BEGIN PUBLIC KEY-----  at the beginning and without  -----END PUBLIC KEY-----    So it causes the error   Initially  my public key was like this   -----BEGIN PUBLIC KEY----- WnsbGUXbb0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71        oNLcaK2wKKyRdcROK7ZTSCSMsJpAFOY -----END PUBLIC KEY-----   But I used just this part   WnsbGUXb b0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71        oNLcaK2w KKyRdcROK7ZTSCSMsJpAFOY
