Encrypt and decrypt text using the Caesar cipher.
Description
Encrypt and decrypt text using the Caesar cipher.
Usage
caesar(text, shift = 3, decrypt = FALSE)
Arguments
text |
String to be ciphered or deciphered. |
shift |
A single whole number for how far to move the characters in the direction (positive or negative) you choose. If not a whole number, it will be rounded to nearest whole number. |
decrypt |
If TRUE, (not default) deciphers the coded text. |
Value
String of the ciphered/deciphered text
Examples
# Please see this for more info.
# https://en.wikipedia.org/wiki/Caesar_cipher
caesar("Experience is the teacher of all things.")
caesar("HAshulhqfhclvcwkhcwhdfkhucricdoocwklqjva", decrypt = TRUE)
caesar("Veni, vidi, vici.", shift = 40)
caesar(",S1WKN9WRWKN9WQWL", shift = 40, decrypt = TRUE)
caesar("No one is so brave that he is not disturbed by something unexpected.", shift = -12)
caesar("Bc[cb:[,g[gc[{f]j:[h>]h[>:[,g[bch[;,ghif{:;[{m[gca:h>,b<[ib:ld:}h:;`",
shift = -12, decrypt = TRUE)
Encrypt and decrypt text using pseudorandom number generation based on the seed set.
Description
Encrypt and decrypt text using pseudorandom number generation based on the seed set.
Usage
seed_cipher(text, seed = 64, decrypt = FALSE)
Arguments
text |
String to be ciphered or deciphered. |
seed |
A single number to set the seed which will pseudorandomly rearrange the original characters |
decrypt |
If TRUE (not default), deciphers the coded text. |
Value
String of the ciphered/deciphered text
Examples
seed_cipher("Cowards die many times before their deaths")
seed_cipher("'Ced<,#G,QhG$dXoG/Q$h#G+h(C<hG/0hQ<G,hd/0#",
decrypt = TRUE)
seed_cipher("Men willingly believe what they wish.",
seed = 2354)
seed_cipher("q39l*D66D9;6.l%36D3d3l*<p4l4<3.l*D <h",
seed = 2354,
decrypt = TRUE)
seed_cipher("the valiant never taste of death but once.",
seed = -100)
seed_cipher("*QDc3f>efk*ckD3D{c*fu*DcS'c]Df*Qcy%*cSkoDi",
seed = -100,
decrypt = TRUE)
