If you are able to, please help decrypt these two ssh2 keys to get the private keys from them.

Here's the first one:

Type: ssh-rsa
Key size: 2048bit
MD5 Fingerprint: 40:b4:65:3a:38:04:61:53:90:c8:c0:ee:aa:8a:f1:75
SHA-256 Fingerprint: k0szLm1ao+s9vIjyJJGOs6+vVbXDfM/zrA9VNRorgr0
Public key:

END SSH2 PUBLIC KEY


Here's the second one:

Type: ssh-dss
Key size: 1024bit
MD5 Fingerprint: 02:80:69:ec:d2:37:37:e1:8d:86:85:72:3c:fe:2b:7e

In 2007 they used 400 computers for a time span of 11 months to break the equivalent of a 700 bit RSA key.

cracking 1024 bit RSA would be month's of cracking of a high tier rig

cracking 2048 bit RSA is only possible with a supercomputer

Besides that this is clearly posted in the wrong forum.
