I'm considering adding support for non-rsa based key exchange to
Roxen's SSL implementation. But the SSL3 spec doesn't contain enough
details or references on DH and DSA signatures and certificates. If
anybody could answer the questions below, or point me to accurate
references, I will be most grateful:
1. How are dsa signatures formatted, when used in the SSL protocol?
One reference to rsaref I have read says that it uses a
concatenation of r and s, each written as a 160 bit string. Is this
the same format used with SSL?
2. What formats are popular for storing dsa keys, in this context? For
RSA keys, I use pkcs#1 key formats (encapsulated using PEM-style
ascii-armoring).
3. What are the formats and object identifiers relevant for
dsa-certificates (i.e. certificates signed using dsa as well as
certificates for dsa keys).
4. When using fixed diffie-hellman parameters, what formats for public
and secret parameters are popular?
5. Formats and object identifiers for certification of diffie-hellman
parameters?
