No, this just updates the name of the key used to encrypt/decrypt the
encrypted key. For example, the encrypted key evm-key is initially
encrypted/decrypted using 'kmk-trusted'. After the update, it is
encrypted/decrypted with 'kmk'. Both now are trusted keys.
$ keyctl show
Session Keyring

117908125 --alswrv 500 -1 \_ keyring: _uid.500
501967942 --alswrv 500 500 \_ trusted: kmk-trusted
317523177 --alswrv 500 500 \_ encrypted: evm-key
666437381 --alswrv 500 500 \_ trusted: kmk
$ keyctl print 317523177

$ keyctl update 317523177 "update trusted:kmk"
$ keyctl print 317523177
trusted:kmk 32 ca0ebb83594f1478146 ....
