Example 98 with UUID

use of java.util.UUID in project cryptomator by cryptomator.

the class WindowsProtectedKeychainAccess method generateSalt.

private byte[] generateSalt() {
    byte[] result = new byte[2 * Long.BYTES];
    UUID uuid = UUID.randomUUID();
    ByteBuffer buf = ByteBuffer.wrap(result);
    buf.putLong(uuid.getMostSignificantBits());
    buf.putLong(uuid.getLeastSignificantBits());
    return result;
}

Example 99 with UUID

use of java.util.UUID in project druid by druid-io.

the class UUIDUtilsTest method validateIsStandardUUID.

public static void validateIsStandardUUID(String uuidString) {
    // Since we strip the "-" from the string, we need to break them back out
    final ArrayList<String> strings = new ArrayList<>();
    strings.add(uuidString.substring(0, 8));
    strings.add(uuidString.substring(8, 12));
    strings.add(uuidString.substring(12, 16));
    strings.add(uuidString.substring(16, 20));
    strings.add(uuidString.substring(20, 32));
    UUID uuid = UUID.fromString(Joiner.on('-').join(strings));
    Assert.assertEquals(uuid.toString().replace("-", ""), uuidString);
}

Example 100 with UUID

use of java.util.UUID in project crate by crate.
