2017-07-07crypto: pk sign with new function from PR838Hans Nilsson
The function pkey_verify_nif handles pk signing with a general approach that is enabled by EVP api in OpenSSL 1.0.0 The rejected PR838 introduced that function and lots of other stuff so far neglected. It also made some different rsa padding methods possible (included). Since the crypto code base has changed significantly, it was an overhelming work to try a git merge. Therefore this commit is a manual move of the source code from the PR into current maint. This commit concentrates to use the new function compatible with the old functions. This includes some #if:s for different versions, compatibility code for 0.9.8. Lacking: test cases, exporting the more general erlang api, documentation...

2017-03-29Fix bug with AES CFB 128Kelly McLaughlin
Fix a bug with the use of the aes_cfb128 cipher by calling the correct underlying openssl interface function when the cipher is specified.
2017-03-29Demonstrate the bug with AES CFB 128 encryptionKelly McLaughlin
Demonstrate a bug with AES CFB 128 for certain key sizes introduced with the Erlang 19.0 release. The code in the block_crypt_nif function in the crypto.c source file incorrectly calls aes_cfb_8_crypt when the specified cipher is aes_cfb8 or aes_cfb128 and the key size is 24 or 32. The aes_cfb_8_crypt function calls the AES_cfb8_encrypt function from the openssl interface, but this is incorrect when the cipher is aes_cfb128. Unfortunately the test cases in the crypto test suite are insufficient to detect an issue like this because it exercises the encryption and decryption roundtrip using the same incorrect underlying function. The problem was observed when trying to update an application to Erlang 19 that attempted to decrypt data that was encrypted using aes_cfb128 by another source. In this commit I altered the crypto test suite to provide a demonstration of this problem.

2016-09-28Support using OpenSSL in FIPS modeDániel Szoboszlay
FIPS mode support needs to be enabled at compile time, by configuring Erlang/OTP with --enable-fips option. In FIPS mode the non-FIPS algorithms are disabled and raise error notsup. The supported protocols list is properly updated in FIPS mode to advertise only the enabled protocols. FIPS mode is off by default even if Erlang/OTP was built with FIPS support. It needs to be turned on at runtime. The official approach is to set the fips_mode application environment parameter of the crypto application to true. This would turn FIPS mode on when the NIF is loaded and would prevent loading the module on error. Another method is provided via the crypto:enable_fips_mode/1 function, but it is not recommended to be used in production, as it won't prevent the use of the crypto module in case of an error, and would risk OpenSSL crashing the emulator. It is very useful for test suites however that need to check both validated and non-validated functionality. This commit is based on commit 00b3a04d17a653b4abddeebd6dd8a2c38df532d0.
2016-09-22Fix compilation when OpenSSL doesn't support RC4Andreas Schultz
When OpenSSL has been configured with the "no-rc4" option, the header file rc4.h doesn't exist, and neither does the rc4 functions. Let's handle those by checking whether OPENSSL_NO_RC4 is defined.
2016-09-19Use more correct delimiters for erl_nif.h includeTuncer Ayaz
Anywhere but the beam sources we shouldn't #include "erl_nif.h", because what "erl_nif.h" does is: (1) fail to find it outside of -I dirs, (2) then treat it as if it was written like <erl_nif.h>. Using <erl_nif.h> skips (1). More information can be found in 6.10.2 of the C standard. Because the examples use "erl_nif.h", NIF projects in the Erlang ecosystem copy this verbatim and make the same mistake.
2016-09-14Fix compilation when OpenSSL doesn't support RC2Magnus Henoch
When OpenSSL has been configured with the "no-rc2" option, the header file rc2.h doesn't exist, and neither does the function EVP_rc2_cbc. Let's handle those by checking whether OPENSSL_NO_RC2 is defined. Also update pbe_SUITE, which uses RC2-CBC in one of the tests.

2016-07-30crypto:cmac calculating the Cipher-based Message Authentication CodePetr Gotthard
The ERL-82 issue requests a way to calculate a CMAC in Erlang. The AES128 CMAC is standartized in RFC 4493 and used e.g. for message authentication in the LoRaWAN networks. The CMAC is implemented by OpenSSL since v1.0.1, but as @IngelaAndin stated in response to the ERL-82, the current crypto implementation does not include functions that call those OpenSSL cryptolib functions. This commit introduces a new function `crypto:cmac` that calls the corresponding OpenSSL functions and calculates the CMAC. Only the cmac_nif is implemented. The incremental functions (init, update, final) are not provided because the current OpenSSL does not allow custom memory allocators like `enif_alloc_resource`. The Erlang user guide states that at least OpenSSL 0.9.8 is required, so I added few #ifdefs so the code is compatible with all versions. However, the OpenSSL pages say that the pre-1.0.1 versions (0.9.8 and 1.0.0) are no longer maintained. Even the 1.0.1 will be retired by Dec 2016. Hence I believe that adding a 1.0.1-only function like CMAC should be OK.
