Same fix as was done for EVP in f4f588683dce36c447017.
|
|
|
|
OpenSSL has deprecated the function RAND_pseudo_bytes used by
crypto:rand_bytes/1, so this function is now deprecated in OTP too.
rand_bytes/3 also used this function, but was not documented
so we can remove it right away.
This commit also removes the fallback in generate_key to use
rand_bytes/1 if strong_rand_bytes/1 throws low entropy.
This is a potential incompatibility but we think it is desirable
as crypto should provide cryptographically secure functions.

This commit enables AES-GCM encryption/decryption to change its tag
length between 1 to 16 bytes.
|
|
|
|
|
|
The FIPS-enabled OpenSSL on RHEL disallows the use of < 256 bit prime
fields (like secp128r1 or secp160k1), and the EC_GROUP_new_cuve_GFp
call would return a NULL pointer for such fields. Not checking for
this failure could result in a segfault in the NIF code.

Using the generic EVP_* API makes it possible to unify
algorithm-specific nif functions to a single generic
function. Effectively the same change that took place on the Erlang
API in R16B01 is now applied to the C code.
The old implementation using the low-level API is kept
for compiling against old OpenSSL,
as parts of the EVP API were introduced in OpenSSL 1.0.0.
There are various minor improvements as well:
- supported algorithms are now provided by the nif code (not a mix of
the C and Erlang code)
- remove unnecessary variables and macro definitions
Most of the changes in this commit comes from Dániel Szoboszlay
https://github.com/dszoboszlay/otp/commit/07f7056f955b324df4ace
which is part of his 'fips' branch.
Now also rebased on master branch.

The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.

that could cause VM crash on faulty input.
|
|
Use a stack allocated context and EVP_CIPHER_CTX_init/cleanup
instead of dynamic EVP_CIPHER_CTX_new/free that does not exist in older
0.9.8 versions.

Despite the confusion caused by the name, aes_cfb_8_crypt and
aes_cfb_128_crypt can use key lengths of 128, 192, or 256. The integer
in the function name refers to the block size for CFB mode. Change
the aes_cfb_8_crypt and aes_cfb_128_crypt functions to accept and use
keys of length 128, 192, or 256. Also augment the existing testing for
these functions using the NIST test vectors for the additional key
lengths to ensure the changes function properly.

* pguyot/fix_srp:
Fix bug in SRP implementation
|
|
sign(dss,) and compute_key(dh,)
|
|
The context was never deallocated.
|
|
SRP didn't work with smaller primes as user secret was improperly
computed.
Formula is: (B - (k * g^x)) ^ (a + (u * x)) % N
Previously, the code computed a + (u * x) % N instead of a + (u * x).
a typically is a 256 bits random number (RFC 5054 says it should be at
least 256 bits), u and x are SHA1 signatures (160 bits). So a + (u * x)
can differ from a + (u * x) % N for N primes smaller than 320 bits.

|
This adds the aes_cfb8 cypher type (and associated tests and
documentation) to the crypto module.
