If you are using this package on a Debian kernel, then everything should be working as expected. See original bug report at:

https://bugs.debian.org/868291

So you should see:

$ grep CONFIG_CRYPTO_USER /boot/config-$(uname -r)  
CONFIG_CRYPTO_USER=m
CONFIG_CRYPTO_USER_API=m
CONFIG_CRYPTO_USER_API_HASH=m
CONFIG_CRYPTO_USER_API_SKCIPHER=m
CONFIG_CRYPTO_USER_API_RNG=m
CONFIG_CRYPTO_USER_API_AEAD=m
