No Github, há uma lista das 10.000 senhas mais comuns. Eu também gerei minha própria lista de senhas aleatórias .

Seu trabalho é identificar a diferença entre as duas listas (com 100% de precisão).

Portanto, seu programa precisa aceitar uma sequência e retornar:

1. Um valor verdadeiro se a senha estiver na lista de senhas comuns
2. Um valor falso se a senha estiver na lista de senhas aleatórias
3. Qualquer coisa que você gostaria se a senha não estivesse

Para os interessados, meu programa gera senhas com 5 a 10 caracteres e cada caractere é uma letra minúscula ou um dígito.

_{Nota: Você não deve usar essas senhas em nada seguro. Meu algoritmo de geração não é seguro e os resultados são publicados on-line para que todos possam ver}

Estou com problemas para testar isso na Retina , então aqui está o Python por enquanto. Teste dando lambdaum nome e executando-o nas listas de palavras:

>>> len([x for x in common if f(x)])
10000
>>> len([x for x in generated if f(x)])
0

É uma regex muito grande, então estou dando um tempo no golfe por um tempo.

Bash - 5324 bytes

gunzip -c rp.gz|grep $1|wc -l

onde rp.gz está localizado em http://dl.tyzoid.com/rp.gz

Isso retorna 1 se na lista aleatória. Isso é falso, pois bash avalia 0 como um valor de verdade.

Parece ser o melhor que consigo descobrir sem quebrar os algoritmos de compactação, e nenhuma das linguagens que gosto de usar realmente possui um breve método de compactação embutido.
