* replace magic magic number used as potentially too small buffer size
by SC_MAX_EXT_APDU_RESP_SIZE
* replace magic number for filename by SC_MAX_PATH_STRING_SIZE
* start error messages with upper-case letters
* use braces after sizeof, i.e. sizeof(X) instead of sizeof X
* fix indentation
* determine DO ID/tag the same way as do_find_tags()
* start error message with upper-case letter
* use sc_strerror(r) instead of plain numeric r in error message
* adapt size of buffer to SC_MAX_EXT_APDU_DATA_SIZE
* determine DO ID/tag the same way as do_find_tags()
* replace magic magic number used as potentially too small buffer size
by SC_MAX_EXT_APDU_RESP_SIZE
* change buffer type from unsigned char to u8 for consistency with
do_put_data() & do_find_tags()
* give ID/tag of DO in error message
* open target file in binary mode
* set default values for variables at declaration time
* replace magic number used as potentially too small buffer size
by SC_MAX_EXT_APDU_RESP_SIZE
* use braces after sizeof, i.e. sizeof(X) instead of sizeof X
* set default values for variables at declaration time
* use sizeof(fid) instead of magic number
* use braces after sizeof, i.e. sizeof(X) instead of sizeof X
* start error message with upper-case letter
* rename from read_and_util_print_binary_file(); adapt callers
* use large enough buffer size SC_MAX_EXT_APDU_RESP_SIZE
instead of potentially too small magic number
* fix spaces before opening curly braces
* avoid special casing SC_CARD_TYPE_BELPIC_EID: a successful read
of an empty file is still a success, even if nothing can get printed
* do not fail on SC_FILE_TYPE_UNKNOWN: be more flexible w.r.t accepting
unknown file types when the preceding card operations succeeded
* fix spaces before opening curly braces
* distinguish between Internal and Working EFs
* add information optionally available in sc_file_t
- record_count
- record_length
- type_attr
* align all labelled values
Replace magic numbers, used as size of PIN-type buffers,
with the symbolic constant SC_MAX_PIN_SIZE, fixing
- readability / understandability
- too small sizes (e.g. for GnuPG cards)
Make opensc-explorer a bit more user friendly by treating the question mark
given as argument to option '--card-driver' special: list all available
drivers instead of stupidly bailing out.
* localize variables
* print errors to stderr
* release allocated resources
* return error code on error - improve non-interactive use
* do not show help on unknown commands when used non-interactively
* make 'interactive' a global variable
* set it when opensc was called with the SCRIPT argument
* document the behaviour in the manual page
Make interactive a global variable and set it in main.
When arguments are given, compare them like ambguous_match() does,
and show the matching ones only.
Add documentation of the 'help' command to the manual page.
In main loop on multiple matches, show help on matching commands only.
* most importantly: immediately return success on exact match
- this allows one command to be a prefix of another one
- it fixes the long-standing breakage between 'find' and 'find_tags'
* fail on second prefix-only match instead of waiting until the end
* check all parameters
* add comments
* inform caller on whether the match was ambiguous or there was no match
* move printing error messages to processing loopt in main()
Accept a file name as a second argument to the 'random' command
to allow storing the generated random bytes to the file given.
Forbid writing binary data to stdout in interactive mode.
* limit buffer to SC_MAX_EXT_APDU_BUFFER_SIZE
* fix buffer length calculation to correctly calculate the available space
* add length checks when parsing passed data into buffer
* consistently show ellipsis for repeatable arguments as 3 dots
* embrace alternative mandatory arguments with curly braces
* use hyphens instead of spaces within non-literal arguments
for improved alignment with the manual page
Let sc_get_challenge() do sc_lock() and loop through the card driver's
get_challenge() until enough bytes were collected. The card driver's
get_challenge() now returns the number of bytes collected (less or equal
than requested) or an error code.
- Allow more code re-use.
- PIV driver now uses ASN.1 parser for reading the random bytes

'int' and 'size_t' (aka 'unsigned long') [-Wsign-compare]

Some cards (e.g., BELPIC) have a hardcoded file length that does not
match the actual file length (e.g., 65535 bytes), and simply return the
data that is actually on the card when asked.
It is useful to still be able to do an ASN.1 decode in that case.
