Off-The-Record (OTR) encryption uses DSA 1024bit (DSA goes up to
only 1024bit, equals ~1320bit RSA) and is not secure for the next
10years or so, or do you want your messages to be
readable/encryptable within your lifetime?<br>
<br>
Solution:<br>
Just use OpenPGP (like gnupg.org's implementation) based 4096bit[1]
RSA encryption and create a new key every few months so you have
your deniability that OTR offers too.<br>
<br>
Or maybe ECC (shorter, comparable, keys), which requires less
computing power, with your own curves, not NIST's ones.<br>
<br>
<br>
[1] Note that even 2048bit RSA keys are equal to ~112bit AES
symmetric keys strength, which is still not safe within ones
lifetime, so 4096bit or more (small patch within gnupg .c file).<br>

<blockquote>RSA claims that 1024-bit keys are likely to become
crackable some time between 2006 and 2010 and that 2048-bit keys
are sufficient until 2030.</blockquote>
