def initialize: (self group) -> void
                      | (String pem_or_der_encoded) -> void
                      | (ec_method ec_method) -> void
                      | (:GFp | :GF2m ec_method, Integer bignum_p, Integer bignum_a, Integer bignum_b) -> void

Creates a new EC::Group object.

If the first argument is :GFp or :GF2m, creates a new curve with given parameters.

Public Instance Methods

(self other) → bool

Returns true if the two groups use the same curve and have the same parameters, false otherwise.

Alias for: eql?

asn1_flag

() → Integer

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6686
def asn1_flag: () -> Integer

Returns the flags set on the group.

See also asn1_flag=.

Source

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6702
def asn1_flag=: (Integer) -> Integer

Sets flags on the group. The flag value is used to determine how to encode the group: encode explicit parameters or named curve using an OID.

The flag value can be either of:

See the OpenSSL documentation for EC_GROUP_set_asn1_flag().

cofactor

() → String

Source

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6723
def curve_name: () -> String

Returns the curve name (short name) corresponding to this group, or nil if OpenSSL does not have an OID associated with the group.

Source

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6741
def eql?: (self other) -> bool

Returns true if the two groups use the same curve and have the same parameters, false otherwise.

Also aliased as: ==

generator

() → Point?

Source

point_conversion_form

() → point_conversion_format

Source

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6771
def point_conversion_form: () -> point_conversion_format

(point_conversion_format format) → point_conversion_format

Source

# File vendor/bundle/ruby/4.0.0/gems/rbs-4.0.3/stdlib/openssl/0/openssl.rbs, line 6795
def point_conversion_form=: (point_conversion_format format) -> point_conversion_format

Sets the form how EC::Point data is encoded as ASN.1 as defined in X9.62.

format can be one of these:

:compressed : Encoded as z||x, where z is an octet indicating which solution of the equation y is. z will be 0x02 or 0x03.

:uncompressed : Encoded as z||x||y, where z is an octet 0x04.

:hybrid : Encodes as z||x||y, where z is an octet indicating which solution of the equation y is. z will be 0x06 or 0x07.
