[BITWARDEN][API] /api/ciphers/create - Browser

Ask the Bitwarden Community
#1

Hi everyone,

I’m trying to re-use some functionality of https://github.com/jcs/rubywarden/blob/master/API.md
Which is a Ruby extension api for bitwarden.

I have succeeded to create an entry in bitwarden with /api/ciphers/create route.

I can create the entry with organisation, folder but no data are posted.
To explain a little, in post data, you should encrypt data with a specific format explains here:
https://github.com/cozy/cozy-stack/blob/master/docs/bitwarden.md.

I used the bitwarden browser plugin with burp to check out routes and data posted. I have found that my data are not well encrypted like bitwarden wanted but I don’t know what is wrong.

Here the ruby code to generate Key and encrypt data:

#PBKDF2 is used with a password of $masterPassword, salt of lowercased $email, and $iterations KDF iterations to stretch password into $masterKey.

def makeKey(password, username, iterations)
  PBKDF2.new(:password => password, :salt => username,
    :iterations => iterations, :hash_function => OpenSSL::Digest::SHA256,
    :key_length => (256 / 8)).bin_string
end

encrypt random bytes with a key to make new encryption key

def makeEncKey(key)
  # pt[0, 32] becomes the cipher encryption key
  # pt[32, 32] becomes the mac key
  plaintext = OpenSSL::Random.random_bytes(64)
  initvector = OpenSSL::Random.random_bytes(16)

  cipher = OpenSSL::Cipher.new "aes-256-cbc-hmac-sha256"
  cipher.encrypt
  cipher.key = key
  cipher.iv = initvector
  ciphertext = cipher.update(plaintext)
  ciphertext << cipher.final

  return cipherString(0, Base64.strict_encode64(initvector), Base64.strict_encode64(ciphertext), nil)
end

#A random, 64-byte key $symmetricKey is created to become the symmetric key. The first 32 bytes become $encKey and the last 32 bytes become $macKey. A random, 16-byte IV $iv is created and $masterKey is used as the key to encrypt $symmetricKey.
#A “CipherString” (a Bitwarden internal format) is created by joining the encryption type (0 for AesCbc256_B64), a dot, the Base64-encoded IV, and the Base64-encoded $encKey and $macKey, with the pipe (|) character to become $protectedKey.

def getmac(cipherString, masterkey)
  if cipherString[0].to_i != 0
    raise "implement #{cipherString[0].to_i} decryption"
  end

  # AesCbc256_HmacSha256_B64
  initvector, ciphertext = cipherString[2 .. -1].split("|", 2)

  initvector = Base64.decode64(initvector)
  ciphertext = Base64.decode64(ciphertext)

  cipher = OpenSSL::Cipher.new "aes-256-cbc-hmac-sha256"
  cipher.decrypt
  cipher.iv = initvector
  cipher.key = masterkey
  plaintext = cipher.update(ciphertext)
  plaintext << cipher.final
  return plaintext[32, 32]
end

def getenckey(cipherString, masterkey)
  if cipherString[0].to_i != 0
    raise "implement #{str[0].to_i} decryption"
  end

  # AesCbc256_HmacSha256_B64
  initvector, ciphertext = cipherString[2 .. -1].split("|", 2)

  initvector = Base64.decode64(initvector)
  ciphertext = Base64.decode64(ciphertext)

  cipher = OpenSSL::Cipher.new "aes-256-cbc-hmac-sha256"
  cipher.decrypt
  cipher.iv = initvector
  cipher.key = masterkey
  plaintext = cipher.update(ciphertext)
  plaintext << cipher.final
  return plaintext[0, 32]
end

encrypt+mac a value with a key and mac key and random iv, return cipherString

def encrypt(pt, key, macKey)
  iv = OpenSSL::Random.random_bytes(16)

  cipher = OpenSSL::Cipher.new "aes-256-cbc-hmac-sha256"
  cipher.encrypt
  cipher.key = key
  cipher.iv = iv
  ct = cipher.update(pt)
  ct << cipher.final

  mac = OpenSSL::HMAC.digest(OpenSSL::Digest.new("SHA256"), macKey, iv + ct)

  return cipherString(2, Base64.strict_encode64(iv), Base64.strict_encode64(ct), Base64.strict_encode64(mac))
end

Do you see something wrong in my encrypt function ? With enckey or mackey ?

i tried to reverse the code of bitwarden browser but didnt find the functions I was interested in

Thanks for your ideas

Best regards

Bitwarden REST API for automated secrets management on self-hosted server
#2

I’m trying to re-use some functionality from "[Bitwarden API Overview] of rubywarden project which is a Ruby API for Bitwarden.

I created an entry in Bitwarden with a /api/ciphers/create route.

I can create the entry with organization, folder but no data is posted.

In my post data, I should encrypt data with a specific format.

I used the Bitwarden browser plugin with Burp to check routes and data being posted. I found that my data are not well encrypted like Bitwarden wanted but I don’t know what is wrong.

Here is the code to generate the key and encrypt data:

There are two functions at the end, you have to enter your url of Bitwarden Server and also your account (email + password). You have also to enter the url of bitwarden to the header Host of the new_item function (request[‘Host’] = “URL_BITWARDEN”)
