<remarks>You are encouraged to use this class for verifying all DSA signatures to ensure code portability with all DSA implementation. Some DSA implementations, like <see cref="T:System.Security.Cryptography.DSACryptoServiceProvider" />, provides some helper methods but these methods will limit your code to use this specific class.</remarks>

<remarks>
<para>
This class only support the <see cref="T:System.Security.Cryptography.SHA1" /> hash algorithm. Any name that resolves in another hash algorithm (or anything else) will throw a <see cref="T:System.Security.Cryptography.CryptographicUnexpectedOperationException" />. This is a restriction of the DSA algorithm (FIPS 186) not of the class library.

<remarks>
<para>
A <see cref="T:System.Security.Cryptography.CryptographicUnexpectedOperationException" /> will be thrown if a <see cref="T:System.Security.Cryptography.DSA" /> object instance hasn't been set in the constructor or by <see cref="M:System.Security.Cryptography.DSASignatureFormatter.SetKey" />.
</para>
<para>
The hash byte array should always have 20 bytes as only the SHA-1 algorithm is supported.
</para>
<para>
The size of the signature, 40 bytes, isn't affected by the length of the public key (512 - 1024 bits).
