In trying to understand the Node.js Crypto API, I have been trying to match code to the equivalent OpenSSL enc command line (line breaks inserted for readability) which is piped through xxd for hex display.  $ echo -n "The quick brown fox jumps o...
Node.js sends the TLS_EMPTY_RENEGOTIATION_INFO_SCSV cipher by default to protect itself against the POODLE attack.  I'm trying to avoid sending this cipher (even though this may pose a security risk) by overriding the TLS ciphers with a custom li...
My question relates to the work by https://stackoverflow.com/users/1142256/nowgoo in an article Encrypt with Cryptico.js, Decrypt with OpenSSL I tried to comment on the original post by nowgoo but I don't have enough clout.  I have prepared a pro...
I'm using this example for javascript encryption using a key generated with the php openssl library, but $details = openssl_pkey_get_details($resource) is returning no public exponent ($details['rsa']['e']).  This is how I'm g...
I have a PHP webpage, where I use OpenSSL to encrypt a text in PHP (openssl_private_decrypt).  Encripted text:     bhYtdNghwutjxqgHg8AoyebLm5AY+X/4GLNzzb0PVuyiUX2QKwwDBXH4kVQFJIqUUrm6nYGk740wWkSoAMzygA==   Public key: -----BEGIN PUBLIC   KEY-----MFww...
I am trying to connect to an SMTP server using TLS to no avail.  I am trying to replicate the following using node: openssl s_client -crlf -starttls smtp -connect smtp.gmail.com:587  I've tried a multitude of different options and parameters but...
Hopefully someone will be good enough to give me a little help here.  I need to generate a 1024 bit RSA key for one time use (gets discarded after each run) and pass the public key to a remote client.  The remote client expects the key to be "in...
I'm building a tool to verify deep links set up with Apple's apple-app-site-association files. In some cases, these files are pkcs7-mime encrypted.  Is there any way currently to decrypt these files entirely on the client? I've researched...
I have some PHP code that produces some ciphertext as follows:  <?php $data = '12345678123456781234567812345678123456781234567812345678123456781234567812345678';  $ciphertext = mcrypt_encrypt('rijndael-128', 'M02cnQ51Ji97vwT4&#...
Someone generated a RSA key pair with the following code using nodejs    export function generateAsymmetric2048KeyPairAsync: (passphrase) {     const options = {         modulusLength: 2048,         publicExponent: 0x10001,         publicKeyEncoding:...
