Example 11 with Log

use of net.i2p.util.Log in project i2p.i2p by i2p.

the class KeyStoreUtil method logCertExpiration.

/**
 *  Validate expiration for all private key certs in a key store.
 *  Use this for keystores containing selfsigned certs where the
 *  user will be expected to renew an expiring cert.
 *  Use this for keystores we are feeding to an SSLContext and ServerSocketFactory.
 *
 *  We added support for self-signed certs in 0.8.3 2011-01, with a 10-year expiration.
 *  We still don't generate them by default. We don't expect anybody's
 *  certs to expire until 2021.
 *
 *  @param location the path or other identifying info, for logging only
 *  @param expiresWithin ms if cert expires within this long, we will log a warning, e.g. 180*24*60*60*1000L
 *  @return true if all are good, false if we logged something
 *  @since 0.9.34

Example 12 with Log

/**
 * Make a repliable I2P datagram containing the specified payload.

 * Format is:
 * <ol>
 * <li>Destination (387+ bytes)
 * <li>Signature (40+ bytes, type and length as implied by signing key type in the Destination)
 * <li>Payload
 * </ol>
 *
 * Maximum datagram size is 32768, so maximum payload size is 32341, or less for
 * non-DSA_SHA1 destinations. Practical maximum is a few KB less due to
 * ElGamal/AES overhead. 10 KB or less is recommended for best results.
 *
 * For DSA_SHA1 Destinations, the signature is of the SHA-256 Hash of the payload.
 *
 * As of 0.9.14, for non-DSA_SHA1 Destinations, the signature is of the payload itself.
 *
 * @param payload non-null Bytes to be contained in the I2P datagram.
