다른 팁

Use 'varchar'

In additon to wallyk's answer,
Exact lengths of encrytpted strings using crypt() are;

Standard DES: stqAdD7zlbByI
Extended DES: _S4..someQXidlBpTUu6
MD5: $1$somethin$4NZKrUlY6r7K7.rdEOZ0w.
Blowfish: $2a$09$anexamplestringforsaleLouKejcjRlExmf1671qw3Khl49R3dfu
SHA-256: $5$rounds=5000$anexamplestringf$KIrctqsxo2wrPg5Ag/hs4jTi4PmoNKQUGWFXlVy9vu9
SHA-512: $6$rounds=5000$anexamplestringf$Oo0skOAdUFXkQxJpwzO05wgRHG0dhuaPBaOU/

It depends on what type of encryption you are using but varbinary is appropriate in some situations.
