But I am getting exception in decrypt, one value out of three already encrypted values using secret key. Exception is: Illegal Block Size Exception Input length must be multiple of 16 when decrypting with padded cipher. Below is my code: Function to encyrpt value public static String symmetricEncrypt(String text, String secretKey) { BASE64Decoder decoder = new BASE64Decoder(); byte[] raw; String encryptedString; SecretKeySpec skeySpec;

The problem I'm facing is that the density plots do not align correctly with the scatter plot due to the missing axes labeling of the density plots and the legend of the scatter plot. It could be adjusted by playing arround with plot.margin . However, this would not be a preferable solution since I would have to adjust it over and over again if changes to the plots are made. Is there a way to position all plots in a way so that the actual plotting

Using the following command I was able to create the following boxplot graph and overlay it with the individual data points: ggplot(data = MYdata, aes(x = Age, y = Richness)) + geom_boxplot(aes(group=Age)) + geom_point(aes(color = Age)) There are several things I would like to add/change: 1. Change the line color and/or fill of each boxplot (depending on "Age") using 6 different colors from left to right: c("#E69F00", "#56B4E9", "#009E73", "

How do I smooth over all data points? 回答1: ggplot(plotData, aes(x, y, label=label, group=label)) + geom_line() + geom_smooth(aes(group = 1)) should do it. The idea here is to provide a new group aesthetic so that the fitted smoother is based on all the data, not the group = label aesthetic. Following the example from @Andrie's Answer the

How can I create my own key? I have tried padding it out to 256 bits, but then I get an error saying that the key is too long. I do have the unlimited jurisdiction patch installed, so thats not the problem :) Ie. The KeyGenerator looks like this ... // Get the KeyGenerator KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(128); // 192 and 256 bits may not be

Target: Plot an image like this: Features: 1. two different time series; 2. the lower panel has a reverse y-axis; 3. shadows over two plots. Possible solutions: 1. Facetting is not appropriate - (1) can not just make one facet's y axis reverse while keep the other(s) unchanges. (2) difficult to adjust the individual facets one by one. 2. Using viewports to arrange individual plots using the following codes: library(ggplot2) library(grid) library(gridExtra) ##Import data df<- read.csv("D:\\R\\SF_Question.csv") #
