Hi,

im considering brain wallet which seed consist of :  todays date, todays time, my name, my email addr, my email pass, my bicointalk nick, my bitcoin talk pass, plus 5 random word.

will it be secure enough Huh

btw : id like to know if we generate a paper wallet does it has time & date stamp  as seed  Huh i think it would be safer from collision that way.

Brainwallets are used for remembering the seed instead of private key in human memory.
Are you sure that a month later you will still remember all these values and their order in seed?

(This question is not for this section. Lets ask moderator to move it to "Beginners & help")
upd: moved. thanks

that way i will only have to remember 5 last word only (ie: i can write it all and ppl will not notice it compared to 12 random word)

Well, basically it's more vulnerable than a normal core wallet.
Because your 12 words can be guessed.

But, both of them have same vulnerability. A very very very very very ... very lucky person can create same address with you and about bitcoin all matters that the public adress's private key.

I recommend you to run bitcoin core wallet and create some public adresses and then dump them and apply them to a payper wallet etc.

I think that you would most likely forget the pass yourself. You're better off etching some additional informaton in steel than trying to memorize everything yourself.

it should be fairly safe so long as u dont forget/mixup the string. its best to use a bitcoin privkey as seed for brain wallet.

i dont think anyone can guess date/time and where exactly im creating the  wallet,  my only concern is that if it is possible for a collision due to private key did not implement time/date as seed (ie:   set time to less than 1990 on computer  then generate wallet which collision would never be possible).

guess i can create from data of my driver licence, plus the data of date and time of making the wallet which will be easier to remember is it Huh

thats the problem if the private key itself did  not take seed from date and time. because time repeat after 24 hours, but day-month-year were infinite, it never repeat.
