The defaults for the public key algorithm is RSA with a 2048 bits.  For
the symmentric session key the default algorithms are
    AES256, AES192, AES256, CAST5-128, 3DES

where gpg picks the best macthing one depending on the capabilities of the
recipients key. If all recipeins have new keys they will all use
AES256. ("new" is measured in years).

Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
