Topic: [SOLVED] possible hack, in the scripting. drops the public key hash. (Read 958 times)

example:
sigscript: OP_1 OP_1 OP_PUSHDATA1 21
explanation:
OP_1 OP_1: to fool OP_EQUALVERIFY
OP_PUSHDATA1 21: the next 21 bytes of data is to be pushed, its all the "OP_DUP OP_HASH160 xxxxxxxx..."
scriptpubkey: OP_DUP OP_HASH160 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx75 OP_EQUALVERIFY OP_CHECKSIG
explanation:
0x75 is 117 in decimal, and also the OP_DROP opcode.
so when this both is put togther:
OP_1 OP_1 OP_PUSHDATA1 21 OP_DUP OP_HASH160 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx75 OP_EQUALVERIFY OP_CHECKSIG
OP_1 OP_1 <21 bytes of data> OP_DROP OP_EQUALVERIFY OP_CHECKSIG
then the public key is indifferent. and you could put a bogus in instead.
will this work?
im worried.
