  +--jssh.RSAPrivateKeyFile

public class RSAPrivateKeyFile

extends java.lang.Object

This class encapsulates the properties and behaviour of an SSH RSA private-key file. The file has the following structure:

• The null-terminated string "SSH PRIVATE KEY FILE FORMAT 1.1\n"
• A single byte indicating the cipher used to encrypt the private key. Possible values are: 0 for no encryption, and 3 for 3DES in CBC mode.
• A 32-bit int ("for future extension").
• Another 32-bit int indicating the number of bits in the key (ignored).
• A multiprecision int (the public modulus)
• A multiprecision int (the public exponent)
• A comment string.
• The remaining bytes of the file contain the private key, encrypted (if the cipher type is nonzero) with the specified cipher.

Method Summary

int	getCipherType()
java.lang.String	getComment()
RSAPrivateKey	getPrivateKey() This method should be called if the key is not encrypted, ie getCipherType() returns SSH_CIPHER_NONE;
RSAPrivateKey	getPrivateKey(java.lang.String passphrase_) This method should be called if the key is encrypted, ie if getCipherType() returns SSH_CIPHER_3DES.
