comment What is the likely cause the RSA algorithm gives back plain text in this case?
Welcome to Cryptography Stack Exchange. Your question is not clear. Usually there is no "small number of encodings" which gives back the plain text, and even less a fixed number of those (which works for any plain text, not just a specific one). From where do you have your assertion (or observation)?

comment Can Pre-Paid Cards be cracked?
Actually, if bridges would collapse every day, this wouldn't be in the headlines anymore :-)

comment Can Pre-Paid Cards be cracked?
I suppose this will depend on the algorithm used by your mobile phone provider. Without any details, this will give only speculation.

comment At the current time, is SHA256 the de facto standard for strong cryptographic hashes?
I changed "encrypted" to "cryptographic" in your question - if you really want to encrypt a hash, you need more than just a hash function.

comment If Bob steals Alice's private key, how exactly would he read her encrypted documents?
I don't know any command line programs which can be used for this, and this would be off-topic here anyways.

comment How exactly would someone crack a private key passphrase?
@Andrew: You quite likely don't want to input a dictionary from the command line. There might be cracking programs with dictionaries out there int the Internet, but this is off-topic here.

comment Where can I find Secp256k1 ECDSA test vectors?
DSA (and ECDSA) is not an encryption algorithm, but a signature algorithm. And this signature is not deterministic ... the best we could do is to give some example signatures which you could verify, or some sample random $k$ together with the signature created from this.
