=head1 DESCRIPTION
|
|
|
|
All provided algorithms get an associated integer identification number.
|
|
This number is dynamic and should be expected to vary from run to run.
|
|
These numbers should only be considered to be unique per provider per
|
|
library context.

=item evp_asym_cipher_get_number()
|
|
|
|
Returns the internal dynamic number assigned to I<cipher>.
|
|
|
|
=item evp_cipher_get_number()

|
|
|
|
Returns the internal dynamic number assigned to I<signature>.
