[tor/master] Rename crypto_pk_check_key(), use it more reasonably, add tests

commit 600e046ed32f9826bcbdf223d99ed8af23a67504 Author: Nick Mathewson <nickm(a)torproject.org> Date: Fri Aug 31 16:15:20 2018 -0400 Rename crypto_pk_check_key(), use it more reasonably, add tests This function was a wrapper around RSA_check_key() in openssl, which checks for invalid RSA private keys (like those where p or q are composite, or where d is not the inverse of e, or where n != p*q). We don't need a function like this in NSS, since unlike OpenSSL, NSS won't let you import a bogus private key. I've renamed the function and changed its return type to make it more reasonable, and added a unit test for trying to read a key where n != p*q. --- src/feature/relay/router.c | 2 +- src/feature/rend/rendservice.c | 2 +- src/lib/crypt_ops/crypto_rsa.h | 2 +- src/lib/crypt_ops/crypto_rsa_nss.c | 15 +++++++--- src/lib/crypt_ops/crypto_rsa_openssl.c | 18 +++++++---- src/test/test_crypto.c | 55 ++++++++++++++++++++++++++++++++++ 6 files changed, 82 insertions(+), 12 deletions(-) diff --git a/src/feature/relay/router.c b/src/feature/relay/router.c index 7685760ac..55e8f1403 100644 --- a/src/feature/relay/router.c +++ b/src/feature/relay/router.c @@ -590,7 +590,7 @@ init_key_from_file(const char *fname, int generate, int severity, tor_log(severity, LD_GENERAL,"Error generating onion key"); goto error; } - if (crypto_pk_check_key(prkey) <= 0) { + if (!
