Pkcs1RsaPublicKey class

PKCS #1 version 2.0 representation of an RSA public key.

This class can be used to:

• Decode a sequence of bytes into the parameters for an RSA public key using the decode constructor; or
• Encode the parameters for an RSA public key into a sequence of bytes using the encode method.

The RSA public key parameters are the modulus and the public exponent.

Format

This binary format is defined in RFC 2437 PKCS #1: RSA Cryptography Specifications, Version 2.0 by this ASN.1 type:

RSAPublicKey ::= SEQUENCE {
  modulus           INTEGER,  -- n
  publicExponent    INTEGER   -- e
}

Where:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

The ASN.1 type is identical in PKCS #1 version 1.5, PKCS #1 version 2.1 and PKCS #1 version 2.2.

PKCS #1 version 2.0 is referenced, because that is the version implemented by Pkcs1RsaPrivateKey.
