Logré identificar la respuesta. Para MySQL
para descifrar:
SELECT CAST(AES_DECRYPT(encrypted-field,'my-encryption-key') as CHAR(50)) from table
cifrar:
SELECT AES_ENCRYPT(encrypted-field,'my-encryption-key') from table;
Para H2:
cifrar:
ENCRYPT('AES', STRINGTOUTF8('<encryption-key>'), STRINGTOUTF8('<text to be encrypted>'))
descifrar:
TRIM(CHAR(0) FROM UTF8TOSTRING(DECRYPT('AES', STRINGTOUTF8('<encryption-key>'), '<text to be encrypted>')))
