There isn't such a feature for H2 unless you are refering to how H2
encrypted database decryption is done via the user password in this
format of "encryption password"<spacing>"database password".
If you are using encryption for H2 database, your JDBC would appear
something like: "jdbc:h2:~/test;cipher=AES;" and the example password
would be "password password" which the 1st "password" refers to the
database encryption password and the 2nd "password" refers to the
database own password.
