How to check which of my products use Blowfish encryption?

Refer to attached article.

Besides reading the product manual, is there any way I can verify if my
products has Blowfish enabled & if TwoFish is supported?

Some of encryption tools we use are Checkpoint & McAfee HDD encryption
(to encrypt laptops & PCs HDDs), Voltage (email encryption), unknown IOS
(for iPhone/iPad) encryption, Winzip (encrypt attachments with password).

Does Veritas Netbackup V7.1 (we do disk to disk/VTL) uses Blowfish
encryption to encrypt the backups?

I suppose this article is not applicable to TLS & SSL encryption or is it?
Or is Blowfish only applicable to encryption of data at rest, not in transit?

The products of most concern to me are:

a) Cisco & Nexus : believe they implement OpenSSH in them
b) Nokia Checkpoint & Juniper firewalls : I think I saw one of my
netadmin colleague ssh into one of them
c) Bluecoat Proxy & Bluecoat MAA : I think they're on Ubuntu Linux
d) Solaris 10 & AIX 7.x : not sure if they're on OpenSSH but they're
running some sort of SSH server
e) McAfee Drive Encryption : I just could not find any mention of
Blowfish (or Twofish) in the product brochure
f) CheckPoint Full Disk Encryption: could not find any mention of
Blowfish (or Twofish) in the product brochure too

For items a-d, if I issue "ssh -vvv target_device_IP", will it reveal
if Blowfish or TwoFish are enabled/available for enabling?

Link above has a list of products that support Twofish (from the developer):
curious if that list is exhaustive ie any product that is not in the above list
do not support Twofish?
