First

I recently started this blog, here is some old work that I thought should be viewed here, work from crackmes.de

Crackmes

Keygenme Två(Tvaa) crackme, recent crackme, some equations, custom blockcipher over GF(2^19).
Solutions: andrewl.us, Encrypto, HMX0101

Seafun Lamagle Keygenme crackme, this crackme I wrote sometime ago. Its about a exploit in the ElGamal scheme.
Solutions: HMX0101

Solutions

dmoon's keygenme 2, solution crackme about GCD algorithm etc.

Encrypto's Aurora, solution colloborated solution, includs some cryptography, reversing a custom cipher etc.

HMX0101's Spare Time, solution .net crackme with a obfusticated XTEA cipher.

freesoul's OwnMe... , solution maths.

Happytown's CrackMe.happytown.VC.0029, solution modular arithmetic.

Cyclops CLR SerialMe 0x01, solution also a cool crackme, plain math, written in .NET, its about a water jug problem.

Cyclops SCORPiON, solution this one is interesting, a modified ICE blockcipher and I a digital signature scheme(Zheng's Signencrypt).

c00lw0lf's CHAOS KeygenMe 8.3: solution quite normal, crackme with RSA314 and two hashes TIGER192 and HAVAL.

Andrewl.us's UPSKiRT, solution about modular arithmetic.

HMX0101's Bored: solution about the Paillier Cryptosystem.
