Answer 1

SSL certificates and cost:

SSL certificates are sometimes cheap and sometimes expensive. It depends on the choice of the certificate and the website in use. If it is a large company or bank, the certificate will be very expensive. If it is a simple blog, or an informational site, it can be cheap. They also come with different validation methods and domains.

There are many SSL certificate providers in trend nowadays. Such as Comodo, GeoTrust, DigiCert, GoDaddy, RapidSSL, etc. They offer services at different levels. Depending on the needs of one's business, company, or website, one should pick them.

Available security encryption and compromised CAs:

There are many security encryption forms available. There is RSA, AES, Triple DES, Twofish, etc. They come with different key sizes and offer strength in terms of various varieties in different forms.

The strongest encryption is known to be AES or advanced encryption standard. This is because when compared with other styles, it offers 10 times better security and is much faster.

Certification authorities that are considered to be more secure are RapidSSL, DigiCert, and Symantec. Apart from this, GeoTrust is also considered secure.

There are many certificate authorities that have been hacked and compromised. Symantec and DigiNotar are some of these.
