r - 生成随 secret 码的函数

Question

我想使用以下函数为员工生成一个随 secret 码。这是我第一次尝试 R 中的函数。所以我需要一些帮助。

genPsw <- function(num, len=8) {
          # Vorgaben für die Passwortkonventionen festlegen
            myArr  <- c("", 2, 3, 4, 5, 6, 7, 8, 9, "A", "B", 
                        "C", "D", "E", "F", "G", "H", "J", "K", "L", "M", 
                        "N", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", 
                        "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o",
                        "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", 
                        "!", "§", "$", "%", "&", "(", ")", "*")
          # replicate is a wrapper for the common use of sapply for repeated evaluation of an expression 
          # (which will usually involve random number generation).
            replicate(num, paste(sample(myArr, size=len, replace=T), collapse=""))
          # nrow of dataframe mitarbeiter 
          dim_mitarbeiter <- nrow(mitarbeiter)
          for(i in 1:dim_mitarbeiter) {
                        # Random Number Generation with i
                          set.seed(i)
                        # Generate Passwort for new variable password
                        mitarbeiter$passwort <- genPsw(i)                
          }

}

根据 Floo0 的答案，我已将函数更改为类似的内容，但它不起作用:

genPsw <- function(num, len=8) {
          # Vorgaben für die Passwortkonventionen festlegen
          sam<-list()
          sam[[1]]<-1:9
          sam[[2]]<-letters
          sam[[3]]<-LETTERS
          sam[[4]]<-c("!", "§", "$", "%", "&", "(", ")", "*")

          # nrow of dataframe mitarbeiter 
          dim_mitarbeiter <- nrow(mitarbeiter)
          for(i in 1:dim_mitarbeiter) {
                        # Random Number Generation with i
                            tmp<-mapply(sample,sam,c(2,2,2,2))
                         # Generate Passwort for new variable password
                        mitarbeiter$passwort <- paste(sample(tmp),collapse="")
          }

}

Answer 1

怎么样

samp<-c(2:9,letters,LETTERS,"!", "§", "$", "%", "&", "(", ")", "*")
paste(sample(samp,8),collapse="")

结果是这样的

"HKF§VvnD"

注意:此方法不强制使用大写、数字和非字母数字符号

编辑:

如果您想强制使用一定数量的大写字母、数字和非字母数字符号，您可以这样做:

sam<-list()
sam[[1]]<-1:9
sam[[2]]<-letters
sam[[3]]<-LETTERS
sam[[4]]<-c("!", "§", "$", "%", "&", "(", ")", "*")

tmp<-mapply(sample,sam,c(2,2,2,2))
paste(sample(tmp),collapse="")

其中c(2,2,2,2)指定数字、字母、大写字母和symbild的数量(按此顺序)。结果:

[1] "j$bP%5R3"

编辑2:要在表中生成新列 mitarbeiter 只需使用

passwort<-replicate(nrow(mitarbeiter),paste(mapply(sample,sam,c(2,2,2,2)),collapse=""))
mitarbeiter$passwort<-passwort
