In some rare randconfig builds, we can end up with ASYMMETRIC_PUBLIC_KEY_SUBTYPE enabled but CRYPTO_AKCIPHER disabled, which fails to link because of the reference to crypto_alloc_akcipher: crypto/built-in.o: In function `public_key_verify_signature': :(.text+0x110e4): undefined reference to `crypto_alloc_akcipher' This adds a Kconfig 'select' statement to ensure the dependency is always there.

as encryption, decryption, signature generation and signature

verification.

This option provides support for asymmetric public key type handling.

If signature generation and/or verification are to be used,

appropriate hash algorithms (such as SHA-1) must be available.

ENOPKG will be reported if the requisite algorithm is unavailable.

This option provides a type of key that can be loaded up from a
|
|
PKCS#7 message - provided the message is signed by a trusted key. If
|
|
it is, the PKCS#7 wrapper is discarded and reading the key returns
|
|
just the payload. If it isn't, adding the key will fail with an
|
|
error.

This is intended for testing the PKCS#7 parser.
