Method Detail

parsePEMPublicKey

public RSAPublicKey parsePEMPublicKey(String pem)
                               throws GeneralSecurityException

Parse a PKCS1 PEM encoded RSA public key into the modulus/exponent components and construct a new RSAPublicKey

Parameters:

pem - The PEM encoded string to parse.

Returns:

a new RSAPublicKey

Throws:

GeneralSecurityException - If an error occurs while parsing the pem argument or creating the RSA key.

getPKCS1Encoded

public byte[] getPKCS1Encoded(RSAPublicKey publicKey)

Return the PKCS1 encoded representation of the specified RSAPublicKey. Since the primary encoding format for RSA public keys is X.509 SubjectPublicKeyInfo, this needs to be converted to PKCS1 by extracting the needed field.

Parameters:

publicKey - The RSA public key to encode.

Returns:

The PKCS1 encoded representation of the publicKey argument
