##### RSA vs. ECC subkeys
GnuPG v2 has full support for Elliptic Curve Cryptography, with ability to
combine ECC subkeys with traditional RSA master keys. The main upside of ECC
cryptography is that it is much faster computationally and creates much
smaller signatures when compared byte for byte with 2048+ bit RSA keys.
GnuPG 2.1 and later has full support for Elliptic Curve Cryptography, with
ability to combine ECC subkeys with traditional RSA master keys. The main
upside of ECC cryptography is that it is much faster computationally and
creates much smaller signatures when compared byte for byte with 2048+ bit RSA
keys.
Unless you plan on using a smartcard device that does not support ECC
operations, we recommend that you create an ECC signing subkey for your kernel
