From 4b8c4f54bbd70849fc91679bea44b4e1dfb0526d Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 18 Oct 2017 20:11:30 +0200 Subject: cipher: remove aes128-ctr NaCl implementation New versions of libsodium have dropped support for aes128-ctr. AES support is only available with OpenSSL now. --- doc/source/manual/config.rst | 1 - src/crypto/cipher/aes128_ctr/CMakeLists.txt | 1 - src/crypto/cipher/aes128_ctr/nacl/CMakeLists.txt | 6 -- .../aes128_ctr/nacl/cipher_aes128_ctr_nacl.c | 76 ---------------------- 4 files changed, 84 deletions(-) delete mode 100644 src/crypto/cipher/aes128_ctr/nacl/CMakeLists.txt delete mode 100644 src/crypto/cipher/aes128_ctr/nacl/cipher_aes128_ctr_nacl.c diff --git a/doc/source/manual/config.rst b/doc/source/manual/config.rst index 0abebeb..94d7a94 100644 --- a/doc/source/manual/config.rst +++ b/doc/source/manual/config.rst @@ -70,7 +70,6 @@ Example config: * ``aes128-ctr``: AES128 in counter mode - ``openssl``: Use implementation from OpenSSL's libcrypto - - ``nacl``: Use implementation from NaCl or libsodium * ``null``: No encryption (for authenticated-only methods using composed_gmac) diff --git a/src/crypto/cipher/aes128_ctr/CMakeLists.txt b/src/crypto/cipher/aes128_ctr/CMakeLists.txt index 0588fed..58e8c6b 100644 --- a/src/crypto/cipher/aes128_ctr/CMakeLists.txt +++ b/src/crypto/cipher/aes128_ctr/CMakeLists.txt @@ -1,3 +1,2 @@ fastd_cipher(aes128-ctr aes128_ctr.c) add_subdirectory(openssl) -add_subdirectory(nacl) diff --git a/src/crypto/cipher/aes128_ctr/nacl/CMakeLists.txt b/src/crypto/cipher/aes128_ctr/nacl/CMakeLists.txt deleted file mode 100644 index 676aa5d..0000000 --- a/src/crypto/cipher/aes128_ctr/nacl/CMakeLists.txt +++ /dev/null @@ -1,6 +0,0 @@ -fastd_cipher_impl(aes128-ctr nacl - cipher_aes128_ctr_nacl.c -) -fastd_cipher_impl_include_directories(aes128-ctr nacl ${NACL_INCLUDE_DIRS}) -fastd_cipher_impl_link_libraries(aes128-ctr nacl ${NACL_LIBRARIES}) -fastd_cipher_impl_require(aes128-ctr nacl NACL) diff --git a/src/crypto/cipher/aes128_ctr/nacl/cipher_aes128_ctr_nacl.c b/src/crypto/cipher/aes128_ctr/nacl/cipher_aes128_ctr_nacl.c deleted file mode 100644 index ead6326..0000000 --- a/src/crypto/cipher/aes128_ctr/nacl/cipher_aes128_ctr_nacl.c +++ /dev/null @@ -1,76 +0,0 @@ -/* - Copyright (c) 2012-2016, Matthias Schiffer - All rights reserved. - - Redistribution and use in source and binary forms, with or without - modification, are permitted provided that the following conditions are met: - - 1.
