The first:
This command will let you enter a string and then output will be a series of encrypted digital.
Encrypted code
python -c 'print reduce(lambda a,b: a*256+ord(b), raw_input("string: "), 0)'
Decrypted code [the number + P]
Digital output P dc -e
The second:
With RCOSR8toZ7nF9Gyc as plain text, encryption in two steps, of course, but also can step off, stay say ~
Encrypted code
echo "RCOSR8toZ7nF9Gyc" |xxd -ps -u
Get: 52434F535238746F5A376E46394779630A
echo "ibase=16;52434F535238746F5A376E46394779630A" |bc
Get: 27992624244640545969914199055074927928074
Previous encrypted code
echo "ibase=16; $(echo "RCOSR8toZ7nF9Gyc" |xxd -ps -u)" |bc
Get: 27992624244640545969914199055074927928074
Decrypted code
dc -e 27992624244640545969914199055074927928074P
Get: RCOSR8toZ7nF9Gyc
Third:
Also used as a plaintext RCOSR8toZ7nF9Gyc, look at the code:
Encrypted code
echo "RCOSR8toZ7nF9Gyc" |base64 -i
Get: Z3RhbGtAZ21haWwuY29tCg ==
Decrypted code
echo "Z3RhbGtAZ21haWwuY29tCg==" |base64 -d
Get: RCOSR8toZ7nF9Gyc
