Good Ol' Fashion Crypto

[theplague42]

History? Cool. I'll get to this eventually; gotta write a paper first.

[Packbat]

Bump #2 - if no-one objects, I'll post a second hint in the morning.

[Packbat]

Okay, so afternoon.

This cipher is of

medium

difficulty.

Code: Select all

ROSNG BGZPA FPCVM AAIEW DEROR PERBT
VGFNS ZIYDE QLGCE DRSAM MQRES NLPCW
DRNZH HOPED BIGBT PRECA WIZSC WERED
RWYDL ZEOAG FFZEG BQKBG IUDEV KDASE
MRDNR KPKNA FBTMN AXAFB FKOPB GWDDW
FNTTC RSGED QLROQ LDEGC OPMRA NLPCW
LEGPA MKILL GDYOI RPGPK NAMZG RYKCP
ROFOI R

The key is the author's name.

[theplague42]

I solemnly swear that I will work on this sometime this week (that includes next Sunday).

[theplague42]

And looks like I epic failed at that. Thread pretty much died. Oh well. This post is mainly a defibrillator post but I'll let it succumb if nothing happens.

[Packbat]

One more clue, then.

Code: Select all

ROSNGBGZP AFPCVMAA IEWDE ROR PERBTVGFNSZ
IYDE QLG CEDRSAMM QRES NL PCW DRNZH. HOP
EDBIG BT PRECAW IZ SCW ERED RWYDLZEOA GF
FZEGBQKBGI UDEV KDA SEMRDNRKP KNA
FBTMNAX; AFBFK OP, BGWDDW, FNTTCR SGED
QLRO QLD EGCOPMRA NL PCW LEGPAM,
KILLGDY, OIR PGPKNAMZGRY KC PROFOIR.

Edit: As you may note, this is not a transposition cipher.

[Packbat]

The final clue: the cipher is a Playfair. If the puzzle isn't solved in a week, I'll go ahead and post the solution and another cryptogram.

[Packbat]

...all right then. The key is Edward Gibbon,

Code: Select all

EDWAR
GIBON
CFHKL
MPQST
UVXYZ

and the plaintext is:

Antoninus diffused order and tranquillity over the greatest part of the earth. His reign is marked by the rare advantage of furnishing very few materials for history; which is, indeed, little more than the register of the crimes, follies, and misfortunes of mankind.

I throw it open to anyone who wants to post a cryptogram before me; otherwise, I'll put one up tomorrow.

[theplague42]

Can I make the next one? It might not be until Sunday but I think I have a good one.

[Packbat]

Okay - I'll post Monday if I don't see anything.

[theplague42]

Alright thanks.

[Packbat]

Okay, new puzzle,

[Packbat]

Bump.

[Meransiel]

Heh, a code with all words having the same number of letters...this should take a while...

[Packbat]

The letters are not broken down into words this time.

[Kcdaspot]

i see COW and TALE in the first two..

and i'm not even close.

[Packbat]

I usually kick things off with letter frequency analysis when I'm cracking ciphers - I know Haschel Cedricson didn't bother for the first one, but I find it useful.

[Packbat]

Bump again. Are people still interested, or should the thread be allowed to fade away?

[theplague42]

Personally, I'd let it fade. We can still keep it in our sigs and someone can find it if they're interested.

I just haven't had the time or will to sit down and work through one.

[Mist7676]

Can I make a code??

[theplague42]

Can I make a code??

If you promise to help promote interest in the thread.

[Mist7676]

Done! Making code in a few minutes

[Mist7676]

Got a code will put it up here later

[theplague42]

You spelled definitely wrong, and the names slightly different Great other than that
