6 Net::SSH::Perl::Key::ECDSA - Elliptical Curve DSA key object base class
7
9 use Net::SSH::Perl::Key;
10 my $key = Net::SSH::Perl::Key->new('ECDSA521');
11
13 Net::SSH::Perl::Key::ECDSA subclasses Net::SSH::Perl::Key to implement
14 the base class of an elliptical curve DSA key object. The underlying
15 implementation is provided by Crypt::PK::ECC, and this class wraps
16 around that module to provide SSH-specific functionality (eg. taking in
17 a Net::SSH::Perl::Buffer blob and transforming it into a key object).
18
20 Net::SSH::Perl::Key::ECDSA implements the interface described in the
21 documentation for Net::SSH::Perl::Key. Any differences or additions are
22 described here.
23
24 $key->read_private($file [, $passphrase])
25 Since this class is a base class, the read_private method reblesses to
26 the subclass based on the key type loaded.
27
28 $key->sign($data)
29 Wraps around Crypt::PK::ECC::sign_message to sign $data using the key
30 $key, then encodes that signature into an SSH-compatible signature
31 blob.
32
33 Returns the signature blob.
34
35 $key->verify($signature, $data)
36 Given a signature blob $signature and the original signed data $data,
37 attempts to verify the signature using the key $key. This wraps around
38 Crypt::PK::ECC::verify_message to perform the core verification.
39
40 $signature should be an SSH-compatible signature blob, as returned from
41 sign; $data should be a string of data, as passed to sign.
42
43 Returns true if the verification succeeds, false otherwise.
