The lists of algothms checked for existence by
modprobe tcrypt mode=1000
generates three bogus errors:
modprobe tcrypt mode=1000
console log:
tcrypt: alg rot13 not found
tcrypt: alg cts not found
tcrypt: alg arc4 not found
rot13 is not an algorithm in the crypto API or tested.
cts is a wrapper, not a base algorithm.
arc4 is named ecb(arc4), not arc4.
Also, the list is missing numerous algorithms that are tested by
other test modes:
blake2b-512
blake2s-256
crct10dif
xxhash64
ghash
cast5
sm4
ansi_prng
Several of the algorithms are only available if
CONFIG_CRYPTO_USER_API_ENABLE_OBSOLETE is enabled:
arc4
khazad
seed
tea, xtea, xeta
Rather that fix that list, remove test mode=1000 entirely.
It seems to have limited utility, and a web search shows no
discussion of anybody using it.
