Open PGP Standard Format PGP Public Key (4096 bit) using SHA-256 hashing algorit

Hello users,

I have been asked by a vendor to provide a “Open PGP Standard Format PGP Public Key (4096 bit) using SHA-256 hashing algorithm”.

In Kleopatra, I have a choice between RSA and DSA. Is this something to ask the vendor? Does it make a difference?

If I choose RSA 4,096 bits: I get an option “+ RSA” (4,096 bits). Do I have to select that option?

If I choose DSA, I only see a 2,048 option. The if I select “+ Elgamal”, I see a 4,096 too

Based on what the vendor has asked me, can you please recommend which option I choose?

Thansk,
PRem

Hi PRem,

your vendor probably refers to RSA, so yes, you can select RSA + RSA 4096 bits.

Background:
The “+RSA” means that both the signing and the encryption key-pairs will be done with the RSA algorithm.

DSA is a different algorithm, with different strength and weaknesses. https://en.wikipedia.org/wiki/Digital_Signature_Algorithm
