Most commonly used OpenPGP symmetric ciphers

[Hasnain Mujtaba]

Hi,

The OpenPGP standard supports many symmetric key algorithms (IDEA,
3-DES, CAST5, AES, Blowfish, SAFER). I was wondering which of these
algorithms are most commonly used in the industry. Is there a most
commonly used algorithm from this list? 

Thanks
Hasnain.
