2017-04-12Rename aes.h to uboot_aes.hStefano Babic
aes.h is a too generic name if this file can be exported and used by a program. Rename it to avoid any conflicts with other files (for example, from openSSL). Signed-off-by: Stefano Babic <sbabic@denx.de>
2014-04-18aes: make apply_cbc_chain_data non-staticStephen Warren
Tegra's crypto.c uses apply_cbc_chain_data() to sign the warm restart code. This function was recently moved into the core aes.c and made static, which prevents the Tegra code from compiling. Make it public again to avoid the compile errors: arch/arm/cpu/tegra20-common/crypto.c: In function ‘sign_object’: arch/arm/cpu/tegra20-common/crypto.c:74:3: warning: implicit declaration of function ‘apply_cbc_chain_data’ [-Wimplicit-function-declaration] arch/arm/cpu/built-in.o: In function `sign_object': .../arch/arm/cpu/tegra20-common/crypto.c:74: undefined reference to `apply_cbc_chain_data' .../arch/arm/cpu/tegra20-common/crypto.c:78: undefined reference to `apply_cbc_chain_data' Fixes: 6e7b9f4fa0ae ("aes: Move the AES-128-CBC encryption function to common code") Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de>
2014-03-21env: Implement support for AES encryption into fw_* toolsMarek Vasut
Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.

2014-03-21aes: Implement AES-128-CBC decryption functionMarek Vasut
Implement a compatible AES-128-CBC decryption function as a counterpart of the encryption function pulled from tegra20-common/crypto.c . Signed-off-by: Marek Vasut <marex@denx.de>
2014-03-21aes: Move the AES-128-CBC encryption function to common codeMarek Vasut
Move the AES-128-CBC encryption function implemented in tegra20-common/crypto.c into lib/aes.c . This is well re-usable common code. Moreover, clean the code up a bit and fix the kerneldoc-style annotations. Signed-off-by: Marek Vasut <marex@denx.de>
2014-03-21aes: Fix kerneldoc for aes.hMarek Vasut
Fix the function annotations in aes.h so they're compatible with kerneldoc. Signed-off-by: Marek Vasut <marex@denx.de>

2012-05-15Add AES crypto libraryYen Lin
Add support for AES using an implementation from Karl Malbrain. This offers small code size (around 5KB on ARM) and supports 128-bit AES only. Signed-off-by: Yen Lin <yelin@nvidia.com> Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
