[github-actions[bot]]

aes-soft has been merged into the aes crate

Details
Status	unmaintained
Package	aes-soft
Version	0.6.4
URL	https://github.com/RustCrypto/block-ciphers/pull/200
Date	2021-04-29

Please use the aes crate going forward. The new repository location is at:

<https://github.com/RustCrypto/block-ciphers/tree/master/aes&gt;

AES-NI is now autodetected at runtime on i686/x86-64 platforms. If AES-NI is not present, the aes crate will fallback to a constant-time portable software implementation.

To force the use of a constant-time portable implementation on these platforms, even if AES-NI is available, use the new force-soft feature of the aes crate to disable autodetection.

See advisory page for additional details.
