Dsa

DSA (Digital Signature Algorithm) is a public-key signature algorithm defined by NIST.

Rsa

RSA is a common public key algorithm, which can be used for encryption and signature

Generation testing note

Example

"Note that checking an rsa signature is faster that checking a dsa or ecdsa one for respective keys length corresponding to the same security level"

from question  

Efficient way to do payload signing in HTML5 SPA

"A dsa signature generation could be somewhat faster than a rsa signature generation maybe up to twice faster"

from question  

What's the most computationally expensive step in a SSH2 session?

"I have made some testing and it came out that rsa is lot slower than dsa"

from question  

What is DSA complexity?

"However dsa verification expect verification calls to be 100x issue is about 10x slower than rsa verification"

from question  

Public key signing algorithm

Others

Example

Use dsa it tends to be more compact than rsa

from question  

Generate reasonable length license key with asymmetric encryption?

After this because there are more options than ssh-dss dsa the client openssh v7 should connect with rsa or better algorithm

from question  

Unable to negotiate with XX.XXX.XX.XX: no matching host key type found. Their offer: ssh-dss

Dsa in general s slower than rsa and ecdsa dsa in general has more perfect or broken states than rsa and dsa in general key generation is several orders of magnitude slower than rsa and ecdsa

from question  

What is wrong with the DSACryptoServiceProvider?

Yes rsa is considered more secure;in october 2014 openssh 7 the default with ubuntu 16.04lts has disabled default support for dsa

from question  

What's the difference between id_rsa.pub and id_dsa.pub?

I guess rsa is older and dsa is newer

from question  

Ssh host key verification failed on one of the clients only

This is why rsa is much slower than dsa

from question  

What is DSA complexity?

Rsa is also a better choice than dsa because it has much better breadth of support for signatures still considered secure by nist

from question  

Get SHA1 sign of string with DSA private key from PEM file

Dsa signatures are signficantly shorter than rsa ones

from question  

Generating short license keys with OpenSSL

Dsa has signature that is independent of key strength and is much smaller than rsa signature for equivalent security rsa 1024 1568 vs dsa 192

from question  

Public key signing algorithm

That continued usage of 1024-bit prime field elgamal or dsa keys is much riskier than it is for 1024-bit rsa all are still commonly used because once a successful attack has been conducted against a single well-chosen prime field all users of that prime field may be affected at little additional effort.

from question  

How to choose prime for implementing Diffie-hellman key exchange

However in this case dsa key size is less than rsa key size
